A state builder.


A convenience widget to rebuild child widget without using Stateful Widget.

builder => return the child widget, which needs to refreshed

routeName => String value for id of parent widget.

holder => a specific String id for a StateBuilder widget. If you have more than one builder in a parent widget and you just wanna refresh one of them, set holder id for it.

This widget always goes with a StateHandler instance as a couple. StateBuilder just like a widget wrapper and StateHandler will control how and when we need to rebuild the child widget. It means you have to declare a StateHandler has same routeName with StateBuilder.

Getting started

Run this command: With Dart:

$ dart pub add flutter_state_builder

With Flutter:

$ flutter pub add flutter_state_builder

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

    flutter_state_builder: ^1.0.0

Alternatively, your editor might support dart pub get or flutter pub get. Check the docs for your editor to learn more.


StateHandler _handler = StateHandler('your_screen_widget_route_name');
    routeName: 'your_screen_widget_route_name',
    builder: () => child_widget,
    holder: 'a_builder_id',
  • StateHandler, which controls the state of a StateBuilder. When you need to rebuild the builder, call this function
