Safety StreamBuilder for Flutter

For lazy, SafetyStreamBuilder can use with just a little confidence.


In StreamBuilder, it is necessary to finely implement whether AsyncSnapshot contains data or an error has occurred. SafetyStreamBuilder provides default blank widget and error display widget and direct data. (hiding AsyncSnapshot)

Before: Using Dart standard StreamBuilder

  stream: stream,
  builder: (BuildContext context, AsyncSnapshot<String> snapshot) {
    if (!snapshot.hasData) {
      return Container();
    if (snapshot.hasError) {
      return Icon(Icons.error_outline);
    return Text(;

After: Using SafetyStreamBuilder

  stream: stream,
  builder: (BuildContext context, String message) => Text(message),
