getIdToken method Null safety

Future<String> getIdToken(
  1. bool forceRefresh
)

Returns a JSON Web Token (JWT) used to identify the user to a Firebase service.

Returns the current token if it has not expired. Otherwise, this will refresh the token and return a new one.

If forceRefresh is true, the token returned will be refresh regardless of token expiration.

Implementation

Future<String> getIdToken(bool forceRefresh) {
  throw UnimplementedError('getIdToken() is not implemented');
}
