将 firebase-core 和 auth 添加到项目后无法运行 flutter 应用程序

Question

Here's the error in console, plus flutter doctor didn't showed any error. I've tried upgraded the android sdk to 28, check build.gradle. It still don't work and I have no clue.

Error

Pubspec.yaml

version: 1.0.0+1

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  google_fonts: ^1.1.1
  path_provider: ^1.6.24
  cupertino_icons: ^0.1.3

dev_dependencies:
  flutter_test:
    sdk: flutter

Answer 1

1- Move them to dependencies

2- Leave a space at the beggining of the dependencie name like so:

dependencies:
  flutter:
    sdk: flutter
    
  firebase_core: ^0.5.1
  firebase_auth: ^0.18.2
  google_fonts: ^1.1.0
  provider: ^4.3.2+2

If you realize, it's like if flutter and the rest of your dependencies were at the same level

Answer 2

Its AAPT issue; Open this open C:\\Users\\user\\Desktop\\Projects\\Flutter\\eLesson\\android\\app\\src\\main\\AndroidManifest.xml and remove style/Theme.AppCompat.Light.NoActionBar

and your App or some of you plugin is not compatible to AndroidX. Open android folder of your project in separate Android Studio. Right click on Project->Refactor->Migrate to AndroidX.

Repeat this process for each of your plugin folder.

Clean and Rebuild.

Enjoy.
