静态Google地图(禁用所有手势) [英] Static Google map (disable all gestures)

问题描述

我想创建一个Google Map小部件，该小部件将不会处理任何点击和手势-只会处理静态地图.我知道我需要某种方式设置 gestureRecognizers ，但无法弄清楚哪个类会锁定所有手势.我应该用什么代替 ScaleGestureRecognizer()?

I want to create a Google Map widget which will not handle any clicks, gestures - just a static map. I understand I need somehow to set gestureRecognizers but can't figure out which class will lock all the gestures. What should I use instead of ScaleGestureRecognizer() ?

将 gestureRecognizers 设置为 null 无济于事.

当此集合为空或为null时，地图将仅处理其他手势识别器未声明的手势的指针事件.

When this set is empty or null, the map will only handle pointer events for gestures that were not claimed by any other gesture recognizer.

import 'package:flutter/cupertino.dart';
import 'package:flutter/foundation.dart';
import 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';

class StaticMap extends StatelessWidget {
  final CameraPosition cameraPosition;
  StaticMap(this.cameraPosition);

  @override
  Widget build(BuildContext context) {
    return GoogleMap(
      mapType: MapType.normal,
      initialCameraPosition: cameraPosition,
      gestureRecognizers: {
        Factory<OneSequenceGestureRecognizer>(() => ScaleGestureRecognizer()),
      },
    );
  }
}

推荐答案

尝试使用 AbsorbPointer

使 AbsorbPointer 的 GoogleMap child 并将其吸收属性设置为 true

Make GoogleMap child of AbsorbPointer and set its absorbing property to true

return AbsorbPointer(
  absorbing: true,
  child: GoogleMap(
    mapType: MapType.normal,
    initialCameraPosition: cameraPosition,
    gestureRecognizers: {
    Factory<OneSequenceGestureRecognizer>(() => ScaleGestureRecognizer()),
    }
  )
);

当您要检测事件时，还可以将其设置为吸收属性 false

You can also set it's absorbing property false when you want to detect events
