Issue
So, I am trying change the default flutter launcher icon with my one. I am using the flutter_launcher_icons: ^0.9.2
from pub.dev.
The code in pubspec.yaml:
dependencies:
flutter:
sdk: flutter
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^1.0.2
hexcolor: ^2.0.5
google_fonts: ^2.1.0
flutter_neumorphic: ^3.2.0
flutter_launcher_icons: ^0.9.2
dev_dependencies:
flutter_lints: ^1.0.4
flutter_test:
sdk: flutter
flutter_icons:
image_path: "assets/icon/icon.png"
android: true
ios: true
But when I am running flutter pub run flutter_launcher_icons:main
, I am getting error saying:
════════════════════════════════════════════
FLUTTER LAUNCHER ICONS (v0.9.1)
════════════════════════════════════════════
✓ Successfully generated launcher icons

pub finished with exit code 255
And the Icon doesn't change.
What probably the problem?
=> I mean, coz it worked many times before...
Solution
Go to android/app/build.gradle
and change the minSdkVersion
and targetSdkVersion
to integer values.
minSdkVersion 21
targetSdkVersion 29
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
Then do the rest, i.e.
pub.get -> flutter pub run flutter_launcher_icons:main
