FloatingWindows

Getting started #

Add to your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  floating_windows: ^1.0.0

Import the package

import 'package:floating_windows/floating_windows.dart';

Usage #

Create a FloatingOverlayController

final controller1 = FloatingOverlayController.absoluteSize(
  maxSize: const Size(800, 800),
  minSize: const Size(400, 300),
  start: Offset.zero,
  padding: const EdgeInsets.all(20.0),
  constrained: true,
);
final controller2 = FloatingOverlayController.absoluteSize(
  maxSize: const Size(800, 800),
  minSize: const Size(400, 300),
  start: const Offset(100, 100),
  padding: const EdgeInsets.all(20.0),
  constrained: true,
);
final controller3 = FloatingOverlayController.absoluteSize(
  maxSize: const Size(800, 800),
  minSize: const Size(300, 500),
  start: const Offset(300, 300),
  padding: const EdgeInsets.all(20.0),
  constrained: true,
);

or

final controller = FloatingOverlayController.relativeSize(
  maxScale: 2.0,
  minScale: 1.0,
  start: Offset.zero,
  padding: const EdgeInsets.all(20.0),
  constrained: true,
);

Insert the FloatingOverlay widget inside your widget tree and give it the controller, a child and floatingChildren.

FloatingOverlay(
  controllers: [controller1, controller2, controller3],
  floatingChildren: [
    SizedBox(
      width: 400,
      height: 300,
      child: Container(
        decoration: BoxDecoration(
          color: Theme.of(context).primaryColor,
          border: Border.all(
            color: Colors.black,
            width: 5.0,
          ),
        ),
      ),
    ),
    SizedBox(
      width: 400,
      height: 300,
      child: Container(
        decoration: BoxDecoration(
          color: Colors.amber,
          border: Border.all(
            color: Colors.black,
            width: 5.0,
          ),
        ),
      ),
    ),
    SizedBox(
      width: 300,
      height: 500,
      child: Container(
        decoration: BoxDecoration(
          color: Colors.red,
          border: Border.all(
            color: Colors.black,
            width: 5.0,
          ),
        ),
      ),
    ),
  ],
  child: Container(),
)

Then use the controller to make the floating child show or hide.

controller.hide();
controller.isFloating;
controller.show();
controller.toggle();
