Erro no Debug do projeto:

Estou lutando com esse erro no Debug do meu projeto:

FAILURE: Build failed with an exception.

* Where:
Script ''''''''''''''''C:\src\flutter\packages\flutter_tools\gradle\flutter.gradle'''''''''''''''' line: 407

* What went wrong:
A problem occurred configuring project '''''''''''''''':cloud_firestore''''''''''''''''.
> Failed to notify project evaluation listener.
> Could not get unknown property ''''''''''''''''android'''''''''''''''' for project '''''''''''''''':cloud_firestore'''''''''''''''' of type org.gradle.api.Project.
> Could not get unknown property ''''''''''''''''android'''''''''''''''' for project '''''''''''''''':cloud_firestore'''''''''''''''' of type org.gradle.api.Project.

Ja tentei varias coisas, mas o ero persiste, o que pode ser?
