A customized GestureDetector that acts on holding a determined Widget.

holding_gesture

A customized GestureDetector that acts on holding a determined Widget.

Getting Started

import 'package:holding_gesture/holding_gesture.dart';

After importing, all you have to do is use HoldDetector the same way you already used GestureDetector! As it is on the documentation, its onTap override won't work when using a child that has onPressed or a similar callback, so you should pass the single tap behaviour to that.

@override
Widget build(BuildContext context) {
  return MaterialApp(
    home: Scaffold(
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Padding(
              padding: const EdgeInsets.all(16.0),
              child: Text(
                'You have pushed (or held) the button this many times:',
                textAlign: TextAlign.center,
              ),
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.display1,
            ),
          ],
        ),
      ),
      floatingActionButton: HoldDetector(
        onHold: _incrementCounter,
        holdTimeout: Duration(milliseconds: 200),
        enableHapticFeedback: true,
        child: FloatingActionButton(
          child: Icon(Icons.add),
          onPressed: _incrementCounter,
      ),
    ),
  ),
);

The main example, above and in example/, is the same as the default Flutter app, with the adition of a haptic feedback to each tick and the ability to hold the button to keep adding to the counter.
