safe<T> method

Future<T?> safe<T>(
  1. Future<T> callback(
    1. CommonDatabase db
    ), {
  2. bool exclusive = true,
  3. String? tag,
})

Runs the callback through a non-closed CommonDatabase, or returns null.

CommonDatabase may be closed, for example, between E2E tests.

Implementation

Future<T?> safe<T>(
  Future<T> Function(CommonDatabase db) callback, {
  bool exclusive = true,
  String? tag,
}) async {
  if (isClosed || db == null) {
    return null;
  }

  return await _provider.wrapped(callback);
}
