The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.
Finished with error: Gradle task assembleDebug failed with exit code 1
回答1:
Make Sure to follow the guide to support AndroidX
https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility
For Solving Dex error
Try adding this line In your Project folder > android > app > build.gradle
add the following Line in multiDexEnabled true
inside defaultConfig
Use flutter clean command once it is done then try running your app.
回答2:
Add following line in gradle.properties
android.useAndroidX=true
android.enableJetifier=true
Remove Simple Permission package.
回答3:
it's because your app isn't compatible with AndroidX ,
There are 2 solution
1-create a flutter compatible with AndroidX app by using this command in your terminal
flutter create --androidx [project_name]
2-configure your app manually
