I am getting this error when I am trying to change the app icon with the "flutter_launcher_icons 0.9.2". I tried specifing the app minsdk and targetsdk but that did not work.I have done flutter pub get several times. After that when I do:flutter pub run flutter_launcher_icons:main. I get this error

This is my pubspec.yaml:

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_launcher_icons: ^0.9.2

flutter_icons:
  android: true
  ios: true
  image_path: "dev_assets/news-logos.jpeg"
  adaptive_icon_background: "#FFFFFF"
  adaptive_icon_foreground: "dev_assets/news-logos.jpeg"

my android/app/build.gradle:

defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.news_app"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }

This seems like a windows error. I have few solutions

  1. Right click on news-logos.jpeg and copy relative path then paste in anywhere that needs it.

  2. Change dev_assets/news-logos.jpeg to dev_assets\news-logos.jpeg as windows doesn't use /

Currently flutter_launcher_icon only support PNG image formate, so may that issue in you app. Try to add PNG image.

Read the error, your path to the file is not correct.

The source of the problem is the inability to provide Assets support for the iOS side of the project. For that open XCode.

Runner > General > App Icons and Launcher Images

You will see the red error in the directory. Create your Assets structure by changing here:

flutter pub get

flutter pub run flutter_launcher_icons:main
