如何在列(或任何可滚动视图)内的FlutterMap (flutter_map包)上使用手势？

dependencies:
  flutter_map: ^0.12.0

import 'package:flutter/material.dart';
import 'package:flutter_map/flutter_map.dart';
import 'package:latlong/latlong.dart';

class MapScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Map'),
      ),
      body: FlutterMap(
        options: MapOptions(
          center: LatLng(51.5, -0.09),
          zoom: 13.0,
        ),
        layers: [
          TileLayerOptions(
            urlTemplate: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
            subdomains: ['a', 'b', 'c'],
          ),
        ],
      ),
    );
  }
}

import 'package:flutter/material.dart';
import 'package:flutter_map/flutter_map.dart';
import 'package:latlong/latlong.dart';

class MapScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Map'),
      ),
      body: GestureDetector(
        onScaleUpdate: (ScaleUpdateDetails details) {
          // 处理缩放手势
          // 可以通过details.scale获取缩放比例
        },
        onPanUpdate: (DragUpdateDetails details) {
          // 处理平移手势
          // 可以通过details.delta获取平移的偏移量
        },
        child: FlutterMap(
          options: MapOptions(
            center: LatLng(51.5, -0.09),
            zoom: 13.0,
          ),
          layers: [
            TileLayerOptions(
              urlTemplate: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
              subdomains: ['a', 'b', 'c'],
            ),
          ],
        ),
      ),
    );
  }
}
