A Flutter State Management solution with dependency injection

Usage

Create your business logic class and place all variables, methods inside it.

import 'package:power_state/power_state.dart';

class CounterController extends PowerController {
  int count = 1;

  increment() {
    count++;
    notifyListeners();
  }
}

Instantiate your class using PowerVault.put(CounterController())

final CounterController controller = PowerVault.put(CounterController());

Then you can use powerBuilder widget in your UI side

 PowerBuilder<CounterController>(
              builder: (countController) {
                return Text(countController.count.toString());
              },
            ),

You can find a Controller that is being used by another page and redirect you to it.

final CounterController countController = PowerVault.find();

You can delete a Controller.

PowerVault.delete<CounterController>();

PowerSelector Widget

PowerSelector allows you to select a specific value listen to. Then when and only when that selected value changes, the widget that returns by the builder method of Selector will rebuild.

PowerSelector<CounterController>(
              <!-- It will listen selectorValue -->
              selector: () => controller.selectorValue,
              builder: (countController) {
                return Text(countController.selectorValue.toString());
              },
 ),
