Gesture Pattern Detector

A Flutter plugin that allows you to detect custom gesture patterns using a Morse code-like string. The plugin supports taps, long presses, and swipes to create complex gesture sequences.

Features

• Recognizes patterns based on taps, long presses, and swipes.
• Customizable timeout for completing the gesture pattern.
• Callback function triggered upon successful pattern detection.

Installation

Add the dependency to your pubspec.yaml file:

dependencies:
  gesture_pattern_detector: any

Run flutter pub get to install the package.

Usage

Wrap your widget with GesturePatternDetector and specify the pattern and callback.

Example

import 'package:flutter/material.dart';
import 'package:gesture_pattern_detector/gesture_pattern_detector.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Gesture Pattern Detector')),
        body: GesturePatternDetector(
          // Define your pattern here
          // pattern: GesturePattern([GestureType.tap,GestureType.long,GestureType.tap]),
          pattern: GesturePattern.parse('><.-'),
          onPattern: () {
            print('Pattern matched!');
            // Action to run when pattern is matched
          },
          child: Container(
            color: Colors.blue,
            height: 200,
            width: 400,
            child: Center(child: Text('Tap or Swipe')),
          ),
        ),
      ),
    );
  }
}

Pattern Syntax

• .: Tap
• -: Long press
• >: Swipe right
• <: Swipe left

Parameters

• pattern (GesturePattern): The gesture pattern to match, using the syntax described above.
• onPattern (VoidCallback): The callback function to execute when the pattern is successfully matched.
• child (Widget): The widget to wrap with the gesture detector.
• timeout (Duration, optional): Time allowed to complete the pattern before it resets (default is 5 seconds).

    required this.onPattern,
    required this.child,
    this.timeout = const Duration(seconds: 5),
    super.key,
