A pragmatic StreamBuilder with sensible defaults

DataStreamBuilder

A pragmatic StreamBuilder with sensible defaults.

It uses three different builders:

• builder: invoked only when stream data is ready (required as parameter)
• loadingBuilder: invoked when waiting for data (not required, the library provides a default)
• errorBuilder: invoked when an error is present in the stream (not required, the library provides a default)

Usage

Using defaults for loading and error states:

DataStreamBuilder<List<Post>>(
  stream: Repository.of<Post>().findAll(),
  builder: (context, List<Post> posts) => ListView(
    children: posts.map((post) => ListTile(title: Text(post.body))).toList(),
  )
)

Custom loading and error widgets:

DataStreamBuilder<List<Post>>(
  stream: Repository.of<Post>().findAll(),
  loadingBuilder: (context) => Center(child: Text('Loading posts...')),
  errorBuilder: (context, error) => PostErrorView(error),
  builder: (context, List<Post> posts) => ListView(
    children: posts.map((post) => ListTile(title: Text(post.body))).toList(),
  )
)
