There are unforgettable memories of every particular activity. We love to treasure the memories through the photos. We also get to share those precious memories with our friends and family with social media accounts. Some pretty clicks may get wasted by the low light or some other problems. A photo editing app can save the moment for us. Just with a few filters, we can get a desirable image set to earn praise from others. Photographs immortalize the memories that fade with time, and Photo editing apps make those images prettier.

Sharing images on social media platforms has become a regular activity nowadays. Many people enjoy sharing their special moments as well as some ordinary moments with their friends and family. Presenting a perfect photo is not only about clicking an ideal picture with the right angle, pose, and light. Any image can be enhanced a bit with the help of a good photo editing app. It has led many mobile app development companies to invest in a photo editing app. The market is flourishing well. There are certain qualities of a photo editing app that makes it worth investing by the customers:

1. Easy-to-use User Interface.

Photo editing app development companies must have a simple user interface to develop a photo editing app. Creating a simple user interface needs a lot of planning. The mobile application development company needs to have the primary features like cropping, editing, rotating on the home page. At the same time, the screen must not be over-clutter. It is always better to show the apps’ features on the get-go to not confuse the users. For photo editing mobile app development, the developers need to have a proper plan from the very beginning.

2. Good Primary Functions.

Many people use the photo editing app for the basics only. The mobile application development companies can incorporate as many features as they want. However, the essential editing functions must be useful. It attracts more users to the applications. The essential functions include crop, straighten, color correction, Red-eye removal, blemish removal, rotate, flip, sharpen, etc. If a photo editing app offers excellent quality in these basic features, more customers will want to use it. The developer can add some extra-ordinary features, but they must make sure that the necessary features are working well. That can be the key to the success of the photo editing app.

3. Attractive and Aesthetic

The design of any website or application is a significant thing to grab the attention of the users. If the app fails to impress the users visually, then the chance of its success decreases majorly. This is why the developer should make sure that the app looks clean and aesthetically beautiful. It does not mean that the app must have a very complicated color scheme, design, and home page. It is always better to make it simple and gorgeous. While making it aesthetically pleasing, the developers should think about making it useful as well. At the same time, the app must be user-friendly. Many visitors may relate their positive first impression with the future experience they will get from using it.

4. Editing Filters

The filters rule social media and photo-sharing applications. A layer of filters can make the pictures look perfect. However, where uploading a better quality photo is an everyday challenge, it is quite natural that the new generation may get bored by the regular filters. It is difficult for the mobile app development companies to add new filters now and then. It requires a lot of market surveys, customers’ views, and experiments. To make it more useful and fun, the developers should keep the option of editing filters. Most photo sharing apps offer several excellent filters. The photo-editing application development companies must involve the users and take out their creators to make a difference. They can also understand the requirement of their pictures and edit their filters accordingly.

5. In-app Picture Clicking

Adding an easy-to-use, in-app picture clicking option on the app’s home page can help it get listed to the users’ favorite. The mobile companies are concentrating on improving camera quality. It is easy to make a high-quality picture look good with filters than to work on a blurry one. With the help of an in-app picture clicking option, the users can check the filers while clicking the photos itself and can adjust the angle, light likewise. This feature can make a photo editing app successful. The developers can also add some more editing options with the in-app picture clicking option.

6. Easy Editing Process

Suppose the developers want to add several editing options and filters. They need to make sure that they do not make the application complex more the users to handle. The photo editing app should have the option to switch between edits. It helps the users to edit multiple photos at the same time. The photo editing app should also have the option to save the users’ latest edits to start from where they left. The photo-editing application development companies can also opt to do the reverse edits to remove the edits quickly they don’t like.

7. Easy Optimization

The best feature of a photo editing app must be its easy optimization. The one-touch features are very popular with users nowadays. People always want to get their work done within a short time. Including the feature of one-touch optimization can impress the majority of the users. The app can suggest the users what filters to use and what edits it requires rather than manually do it. If the app can fix a photo on its own, it is helpful for many users who are using the app for essential works like cropping, rotating, etc.

Though several factors help a photo editing app to succeed, user-friendliness is the quality that attracts most of the customers. Simultaneously, photo editing app development, developers need to concentrate on making the app simple and aesthetically beautiful. To develop a photo editing app, the Mobile app development company should create a platform that provides the customers with a good experience.

In the first week of 11 weeks of Android, it has lots of new features that are included new notifications & new sign-in feature as well. This article is focused on the new conversation notification feature that is available in the upcoming Android OS version 11.

What’s New!

Stay in touch with your loved once with the new conversation notification feature. Show conversation with people with the use of a bubble (Eg. Facebook messenger). The goal of this new feature is to The People in your life feel like they’re right there with you. With the use of conversation, you’ll be able to start a new conversation through the pinnable shortcut that is available in the conversation section in the notification pan.

Check updates of conversation which will now appear above notification in notification pan. Also, you can switch to any conversation you had with your loved once without switching through the other apps with the use of a bubble.

How to

Now we will see how to build a conversation shortcuts.

• First, you need to publish a shortcut and set it as longlived so it can be used across OS features.
• Shortcuts are a combination of metadata and properties.
• Publish regular shortcuts with essential details like icon, name & intent, hence these details are optional, it is not mandatory to add these details.
• Set longlived as true so the Operating System knows to keep track of that conversation.

 

Manage shortcuts

• Shortcuts that are set as longlived are stored in the system cache.
• Developers are also can remove cached conversations programmatically with the use ofremovelongLivedShortcuts().
• But cache shortcuts can only be removed if the user has no longer access to that conversation.

Awesome things can be done with the conversation shortcuts

• Aside from being pinned on the launcher, conversations are also meant to appear in the notification bar above the notifications.
• Conversation notifications make it easier to see the sender’s avatar, name, and message.
• Conversations are also prioritized on the sharing menu.

There have been various tools released for cross-platform development over the years, including web-based tools such as PhoneGap from Adobe, powerful frameworks such as Xamarin from Microsoft, and newer tools such as React Native from Facebook. Each toolset has pros and cons and they have met with varying degrees of success in the mobile industry.

Flutter from Google is a recent framework to enter the cross-platform arena, which was announced in February at Mobile World Congress 2018 to be entering a beta phase. Features of Flutter are fast development cycles, fast UI rendering and unique UI design, and native app performance on both platforms.

Introduction to Flutter

Dart programming language is used to write Flutter apps that are originally from Google and now an ECMA standard. Dart language is somewhat similar to languages like Kotlin and Swift and can be trans compiled into JavaScript code.

Getting Started

Flutter application development can be done on Windows, Linux, or macOS. While you can use any editor with the Flutter toolchain, there are IDE plugins for IntelliJ IDEA, Android Studio and Visual Studio Code that can ease the development cycle. We’ll use Android Studio for this tutorial.

Set up an editor

install the Flutter and Dart plugins

To install these:

• Start Android Studio.
• Open plugin preferences (File > Settings > Plugins on Windows & Linux, Preferences > Plugins on macOS,).
• Select Browse repositories, select Flutter plugin and click Install.
• Click Yes to install the Dart plugin.
• Click Restart when prompted.

Create the app

• Select the File > New Flutter Project.
• Select project type – Flutter application, and press Next.
• Make sure Flutter SDK Path text field specifies the location of the SDK. Install the SDK if it is not installed.
• Enter a project name (for example, myapp), and press Next.
• Click Finish.
• Wait until Android Studio installs the SDK, and create the project.

1. main.dart

import 'package:flutter/material.dart';

void main() => runApp(new FlutterApp());


class FlutterApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
	return new MaterialApp(
  	title: 'Flutter',
  	home: new Scaffold(
    	appBar: new AppBar(
      	title: new Text('Flutter'),
    	),
    	body: new Center(
      	child: new Text('Flutter'),
    	),
  	),
	);
  }
}

The main() function near the top uses the => operator for a single line function to run the app. You have a class for the app named GHFlutterApp.

You see here that your app itself is a StatelessWidget. almost every entities in a Flutter app are widgets, either stateless or stateful.  Override the widget build() method to create your app widget. You’re using the MaterialApp widget that provides a number of components needed for apps following Material Design.

For this getting started tutorial, remove the test file widget_test.dart in the test folder from the project by selecting it and hitting the Delete key.

If you’re on macOS, startup the iOS simulator. You can also use an Android emulator on macOS, Linux, or Windows.

2. Hot Reload

The best aspect of Flutter development is being able to hot reload your app as you make changes. This is like Android Studio’s Instant Run.

3. Widgets

Almost every element of your Flutter app is a widget. Widgets are immutable, since using immutable widgets helps keep the app UI lightweight.

There are two fundamental types of widgets you will use:

Stateless widgets are immutable, meaning that their properties can’t change—all values are final. [1]

Stateful widgets maintain state that might change during the lifetime of the widget. [1]

Stateless and stateful widgets are redrawn in Flutter apps on every frame, the difference being that the stateful widgets delegate their configuration to a State object.

To get started with making your own widgets create a new class at the bottom of main.dart:

class GHFlutter extends StatefulWidget {
  @override
  createState() => new GHFlutterState();
}

You have made a StatefulWidget subclass and you’re overriding the createState() method to create its state object. Now add a GHFlutterState class above GHFlutter:

class GHFlutterState extends State<GHFlutter> {
}

Add a build() override to GHFlutterState:

@override
Widget build(BuildContext context) {
   
}

Fill out build() as follows:

@override
Widget build(BuildContext context) {
  return new Scaffold (
	appBar: new AppBar(
  	title: new Text(Strings.appTitle),
	),
	body: new Text(Strings.appTitle),
  );
}

A Scaffold is a container for material design widgets. It acts as the root of a widget hierarchy. You’ve added an AppBar and a body to the scaffold, and each contains a Text widget.

Update GHFlutterApp class so that it uses your new GHFlutter widget as its home attribute, instead of building a scaffold of its own:

class GHFlutterApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
	return new MaterialApp(
  	title: Strings.appTitle,
  	home: new GHFlutter(),
	);
  }
}

4. Making Network Calls

Earlier you imported your own strings.dart file into the project. You can similarly import other packages that are part of the Flutter framework and Dart.

For example, you’ll now use packages available in the framework to make an HTTP network call and also parse the resulting response JSON into Dart objects. Add two new imports at the top of main.dart:

import 'dart:convert';

import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;

import 'strings.dart';

Dart apps are single-threaded, but Dart provides support for running code on other threads as well as running asynchronous code that does not block the UI thread using an async/await pattern.

You’re going to make an asynchronous network call to retrieve a list of GitHub team members. Add an empty list as a property at the top of GHFlutterState, and also add a property to hold a text style:

var _members = [];

final _biggerFont = const TextStyle(fontSize: 18.0);

The underscores at the beginning of the names make the members of the class private.

To make the asynchronous HTTP call, add a method _loadData() to GHFlutterState:

_loadData() async {
  String dataURL = "https://api.github.com/orgs/raywenderlich/members";
  http.Response response = await http.get(dataURL);
  setState(() {
	_members = JSON.decode(response.body);
  });
}

The underscores at the beginning of the names make the members of the class private.

To make the asynchronous HTTP call, add a method _loadData() to GHFlutterState:

_loadData() async {
  String dataURL = "https://api.github.com/orgs/raywenderlich/members";
  http.Response response = await http.get(dataURL);
  setState(() {
	_members = json.decode(response.body);
  });
}

You’ve added the async keyword onto _loadData() to tell Dart that it’s asynchronous, and also the await keyword on the http.get() call that is blocking. You’re using a dataUrl value that is set to the GitHub API endpoint that retrieves members for a GitHub organization.

When the HTTP call completes, you pass a callback to setState() that runs synchronously on the UI thread. In this case, you are decoding the JSON response and assigning it to the _members list.

Add an initState() override to GHFlutterState that calls _loadData() when the state is initialized:

@override
void initState() {
  super.initState();

  _loadData();
}

5. Using a ListView

Now that you have a Dart list of members, you need a way to display them in a list in the UI. Dart provides a ListView widget that will let you show the data in a list. ListView acts like a RecyclerView on Android and a UITableView on iOS, recycling views as the user scrolls through the list to achieve smooth scrolling performance.

Add a _buildRow() method to GHFlutterState:

Widget _buildRow(int i) {
  return new ListTile(
	title: new Text("${_members[i]["login"]}", style: _biggerFont)
  );
}

You are returning a ListTile widget that shows the “login” value parsed from the JSON for the ith member, and also using the text style you created before.

Update the build method to have it’s body be a ListView.builder:

body: new ListView.builder(
  padding: const EdgeInsets.all(16.0),
  itemCount: _members.length,
  itemBuilder: (BuildContext context, int position) {
	return _buildRow(position);
  }),

That’s just how easy it is to make a network call, parse the data, and show the results in a list!

6. Adding dividers

To add dividers into the list, you’re going to double the item count, and then return a Divider widget when the position in the list is odd:

body: new ListView.builder(
  itemCount: _members.length * 2,
  itemBuilder: (BuildContext context, int position) {
	if (position.isOdd) return new Divider();

	final index = position ~/ 2;

	return _buildRow(index);
  }),

Be sure not to miss the * 2 on itemCount. You’ve removed padding from the builder now that you have dividers. In itemBuilder, you’re either returning a Divider(), or instead calculating a new index by integer division and using _buildRow() to build a row item.
