stream_state 0.0.1

A very thin wrapper around streams for simple but easy to use state management.

StreamState

StreamState is an extremely thin wrapper around streams to make them a very simple but easy to use state management option.

How to use

To add some new bit of state simply create a StreamState with an initial value:

    var counter = StreamState<int>(initial: 0);
    var useRedText = StreamState<bool>(initial: true);

It is very easy to update the state:

    counter++;
    useRedText = !useRedText;

StreamStateBuilders will automatically update your UI when the state changes:

    StreamStateBuilder<bool>(
        streamState: useRedText,
        builder: (context, useRedTextState) => StreamStateBuilder<int>(
            streamState: counter,
            builder: (context, counterState) => Text(
                counterState.toString(),
                style: TextStyle(color: useRedTextState ? Colors.red : null),
        ), //StreamStateBuilder
    ), //StreamStateBuilder

Included Example

The included counter example uses a singleton to store the state for simplicity. This makes it very easy to access your state from anywhere in your app. You can create as many of these singletons as you'd like to separate the logic of your code.

You could also store your StreamStates in any other way, including just in a stateful widget.
