Grave error en la compilación

[LuisRobertoNavarro]

el solo echo de agregar external_app_launcher 4.0.0 en un projecto total mente en blanco, recién iniciado. No permite la compilación en flutter. En modo debug funcionaría, pero cuando se realiza flutter run --release habiendo incorporado este paquete, genera el siguiente error: FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':external_app_launcher:verifyReleaseResources'.

A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action
Android resource linking failed
ERROR: /Users/luisrobertonavarro/Desktop/Des/Pruebas/flutter_application_11/build/external_app_launcher/intermediates/merged_res/release/values/values.xml:194: AAPT: error: resource android:attr/lStar not found.

No permitiendo la compilación, si no mal interpreto por los mensajes de error este paquete "external_app_launcher 4.0.0" ya no es compatible con el gradle actual de flutter.
