1.GestureDetector单击手势

序列号 字段 属性 描述
1 onTapDown GestureTapDownCallback 手指按下时的回调函数
2 onTapUp GestureTapUpCallback 手指松开时的回调函数
3 onTap GestureTapCallback 手指点击时的回调函数
4 onTapCancel GestureTapCancelCallback 手指取消点击时的回调函数

我们在Container容器上添加了单击手势，代码如下：

import 'package:flutter/material.dart';

class GestureDetectorExample extends StatefulWidget {
  @override
  _GestureDetectorExampleState createState() => _GestureDetectorExampleState();
}

class _GestureDetectorExampleState extends State<GestureDetectorExample> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("GestureDetector"),
      ),
      body: Center(
        child: Stack(
          children: [
            GestureDetector(
              onTap: (){
                print("onTap");
              },
              onTapCancel: () {
                print("onTapCancel");
              },
              onTapDown: (details) {
                print("onTapDown---${details.globalPosition}---${details.localPosition}");
              },
              onTapUp: (details) {
                print("onTapUp---${details.globalPosition}---${details.localPosition}");
              },
              child: Container(
                width: 200,
                height: 200,
                color: Colors.orange,
                alignment: Alignment.center,
                child: Text("Jimi",
                  style: TextStyle(
                    color: Colors.white,
                    fontSize: 30
                  ),
                ),
              ),
            )
          ],
        ),
      ),
    );
  }
}

GestureDetector单击手势控制台输出结果

第一种：点击Container容器

flutter: onTapDown---Offset(211.5, 317.0)---Offset(124.0, 45.5)
flutter: onTapUp---Offset(211.5, 317.0)---Offset(124.0, 45.5)

2.GestureDetector双击手势

序列号 字段 属性 描述
1 onDoubleTapDown GestureTapDownCallback 手指按下时的回调函数
2 onDoubleTap GestureTapCallback 手指双击时的回调函数
3 onDoubleTapCancel GestureTapCancelCallback 手指取消时的回调函数

我们在Container容器上添加了三种双击手势的回调，代码如下：

import 'package:flutter/material.dart';

class GestureDetectorExample extends StatefulWidget {
  @override
  _GestureDetectorExampleState createState() => _GestureDetectorExampleState();
}

class _GestureDetectorExampleState extends State<GestureDetectorExample> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("GestureDetector"),
      ),
      body: Center(
        child: Stack(
          children: [
            GestureDetector(
              onDoubleTap: () {
                print("onTapDown");
              },
              onDoubleTapCancel: () {
                print("onDoubleTapCancel");
              },
              onDoubleTapDown: (details) {
                print("onDoubleTapDown---${details.globalPosition}---${details.localPosition}");
              },
              child: Container(
                width: 200,
                height: 200,
                color: Colors.orange,
                alignment: Alignment.center,
                child: Text("Jimi",
                  style: TextStyle(
                      color: Colors.white,
                      fontSize: 30
                  ),
                ),
              ),
            )
          ],
        ),
      ),
    );
  }
}

1 onScaleStart GestureScaleStartCallback 开始缩放时的回调函数
2 onScaleUpdate GestureScaleUpdateCallback 缩放移动时的回调函数
3 onScaleEnd GestureScaleEndCallback 缩放结束时的回调函数

我们在Container容器上添加了缩放手势，代码如下：:

import 'package:flutter/material.dart';

class GestureDetectorExample extends StatefulWidget {
  @override
  _GestureDetectorExampleState createState() => _GestureDetectorExampleState();
}

class _GestureDetectorExampleState extends State<GestureDetectorExample> {

  double _left = 0;
  double _top = 0;
  double _widthAndHeight = 200;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("GestureDetector"),
      ),
      body: Center(
        child: Stack(
          children: [
            /// 缩放手势
            GestureDetector(
              onScaleEnd: (details) {
                print("onScaleEnd---${details.velocity}---${details.pointerCount}");
              },
              onScaleStart: (details) {
                print("onScaleStart---${details.focalPoint}---${details.pointerCount}");
              },
              onScaleUpdate: (details) {
                print("onScaleUpdate---${details.scale}---${details.scale.clamp(0.1, 1.2)}");
                setState(() {
                  _widthAndHeight = 200 * details.scale.clamp(0.3, 1.8);
                });
              },
              child: Container(
                width: _widthAndHeight,
                height: _widthAndHeight,
                color: Colors.orange,
                alignment: Alignment.center,
                child: Text("Jimi",
                  style: TextStyle(
                      color: Colors.white,
                      fontSize: 30
                  ),
                ),
              ),
