configure method

Future<void> configure(String projectId, { List<String>? platforms, String? env, })

Configures FlutterFire for the current project using the provided projectId.

Includes exponential backoff retry logic to handle cases where a newly created project's API hasn't propagated across Google's backend yet.

The platforms parameter specifies which platforms to configure (e.g., 'android', 'ios', 'macos', 'web', 'windows').

The env parameter specifies the target environment name (e.g., 'dev').
