const QueryListenableBuilder<T>(
  1. {Key? key,
  2. WidgetBuilder? pendingBuilder,
  3. WidgetBuilder? waitingBuilder,
  4. FailedResultBuilder? failedBuilder,
  5. required ValueResultBuilder<T> builder,
  6. required ValueListenable<AsyncQueryResult<T>> listenable}
)

Implementation

const QueryListenableBuilder({
  Key? key,
  this.pendingBuilder,
  this.waitingBuilder,
