bloc_streambuilder
A stream builder that uses the value of a ValueObservable as initial data. This builder in combination with ValueSubject makes sure that the streambuilder does not need to build twice when the stream already has a value.
Example
ValueObservable<int> stream = ValueSubject(seedValue: 0);
ValueObservableBuilder(
builder: (context, snapshot) { // Only called once and immediately with data if the stream has data
print(
"Build called with data: ${snapshot.data}, connectionState: ${snapshot.connectionState}"
); // First time it prints "Build called with data: 0, connectionState: ConnectionState.active"
return new Text('${snapshot.data}');
},
stream: stream,
)
