✓ Successfully generated launcher icons , Unhandled exception: FileSystemException: Cannot open file, path = 'dev_assets/news-logos.jpeg'

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
    }

Full error:

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

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

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 /

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