Safety StreamBuilder for Flutter

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

Usage

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

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

After: Using SafetyStreamBuilder

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