If I want to change the app icon,

Answer 1

Flutter Launcher Icons has been designed to help quickly generate launcher icons for both Android and iOS: https://pub.dartlang.org/packages/flutter_launcher_icons

• Add the package to your pubspec.yaml file (within your Flutter project) to use it
• Within pubspec.yaml file specify the path of the icon you wish to use for the app and then choose whether you want to use the icon for the iOS app, Android app or both.
• Run the package
• Voila! The default launcher icons have now been replaced with your custom icon

I'm hoping to add a video to the GitHub README to demonstrate it

Video showing how to run the tool can be found here.

If anyone wants to suggest improvements / report bugs, please add it as an issue on the GitHub project.

Update: As of Wednesday 24th January 2018, you should be able to create new icons without overriding the old existing launcher icons in your Flutter project.

Update 2: As of v0.4.0 (8th June 2018) you can specify one image for your Android icon and a separate image for your iOS icon.

Update 3: As of v0.5.2 (20th June 2018) you can now add adaptive launcher icons for the Android app of your Flutter project

Best & Recommended way to set App Icon in Flutter.

I found one plugin to set app icon in flutter named flutter_launcher_icons. We can use this plugin to set the app icon in flutter.

1. Add this plugin in pubspec.yaml file in project root directory. Please check below code,

dependencies:    
 flutter:    
  sdk: flutter    
 cupertino_icons: ^0.1.2    
 flutter_launcher_icons: ^0.7.2+1**    

Save the file and run flutter pub get on terminal.

2. Create a folder assets in the root of the project in folder assets also create a folder icon and place your app icon inside this folder. I will recommend to user 1024x1024 app icon size. I have placed app icon inside icon folder and now I have app icon path as assets/icon/icon.png

3. Now, in pubspec.yaml add the below code,

flutter_icons:    
 android: "launcher_icon"    
 ios: true    
 image_path: "assets/icon/icon.png"

4. Save the file and run flutter pub get on terminal. After running command run second command as below

flutter pub run flutter_launcher_icons:main -f pubspec.yaml 

Then Run App

I have changed it in the following steps:

1) please add this dependency on your pubspec.yaml page

 dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_launcher_icons: ^0.7.4

2) you have to upload an image/icon on your project which you want to see as a launcher icon. (i have created a folder name:image in my project then upload the logo.png in the image folder). Now you have to add the below codes and paste your image path on image_path: in pubspec.yaml page.

flutter_icons:
  image_path: "images/logo.png"
  android: true
  ios: true

3) Go to terminal and execute this command:

flutter pub get

4) After executing the command then enter below command:

flutter pub run flutter_launcher_icons:main

5) Done

N.B: (of course add an updated dependency from

https://pub.dev/packages/flutter_launcher_icons#-installing-tab-

)

Follow simple steps:

1. Add flutter_launcher_icons Plugin to pubspec.yaml

e.g.

  ios: true

2. Prepare an app icon for the specified path. e.g. icon/icon.png

3. Execute command on the terminal to Create app icons:
