Flutter startup Error: uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library

I allready tried to change the minSdkVersion from 16 to 19 and to 21 (as flutter suggest this as a fix to that problem in the terminal). I also tried to let flutter rebuild the android folder with flutter.create . and I completely reinstalled flutter. I also changed my compileSdkVersion from 32 to 31 and did the same thing with the targetSdkVersion. But the error still occures.

The full error:

Launching lib\main.dart on sdk gphone64 x86 64 in debug mode...
Running Gradle task 'assembleDebug'...
C:\Flutter\test_project\android\app\src\debug\AndroidManifest.xml Error:
    uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [:cloud_firestore] C:\Flutter\test_project\build\cloud_firestore\intermediates\merged_manifest\debug\AndroidManifest.xml as the library might be using APIs not available in 16
    Suggestion: use a compatible library with a minSdk of at most 16,
        or increase this project's minSdk version to at least 19,
        or use tools:overrideLibrary="io.flutter.plugins.firebase.firestore" to force usage (may lead to runtime failures)

FAILURE: Build failed with an exception.

* What went wrong:

            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}
