包括了所有级别的行政区划：省、邦、直辖区、县、镇区、城镇、乡村。

使用方法

1. 导入包

在你的 pubspec.yaml 文件中添加依赖：

dependencies:
  flutter:
    sdk: flutter
  myanmar_administrative_areas: ^1.0.0

然后运行 flutter pub get 来获取依赖包。

2. 基本示例

示例 1: 选择省份和城镇

更多关于Flutter缅甸行政区划插件myanmar_administrative_areas的使用的实战系列教程也可以访问 https://www.itying.com/category-92-b0.html

myanmar_administrative_areas 是一个用于获取缅甸行政区划信息的 Flutter 插件。它可以帮助开发者轻松地获取缅甸的省、市、区等行政区划数据。以下是如何使用该插件的基本步骤：

1. 添加依赖项

首先，你需要在 pubspec.yaml 文件中添加 myanmar_administrative_areas 插件的依赖项。

dependencies:
  flutter:
    sdk: flutter
  myanmar_administrative_areas: ^1.0.0  # 使用最新版本号

然后运行 flutter pub get 来获取依赖项。

2. 导入插件

在你的 Dart 文件中导入插件：

import 'package:myanmar_administrative_areas/myanmar_administrative_areas.dart';

3. 使用插件

你可以使用 MyanmarAdministrativeAreas 类来获取缅甸的行政区划信息。以下是一些常见的使用示例：

获取所有省/邦

List<Region> regions = MyanmarAdministrativeAreas.getAllRegions();
for (var region in regions) {
  print(region.name); // 打印省/邦的名称
}

获取某个省/邦下的所有市/镇

List<Township> townships = MyanmarAdministrativeAreas.getTownshipsByRegionId(regionId);
for (var township in townships) {
  print(township.name); // 打印市/镇的名称
}

获取某个市/镇下的所有区/村

List<Ward> wards = MyanmarAdministrativeAreas.getWardsByTownshipId(townshipId);
for (var ward in wards) {
  print(ward.name); // 打印区/村的名称
}

4. 示例代码

以下是一个完整的示例，展示如何获取并显示缅甸的行政区划信息：

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

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

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('缅甸行政区划'),
        ),
        body: MyanmarAdministrativeAreasExample(),
      ),
    );
  }
}

class MyanmarAdministrativeAreasExample extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    // 获取所有省/邦
    List<Region> regions = MyanmarAdministrativeAreas.getAllRegions();

    return ListView.builder(
      itemCount: regions.length,
      itemBuilder: (context, index) {
        Region region = regions[index];
        return ExpansionTile(
          title: Text(region.name),
          children: [
            // 获取该省/邦下的所有市/镇
            ...MyanmarAdministrativeAreas.getTownshipsByRegionId(region.id).map((township) {
              return ListTile(
                title: Text(township.name),
                subtitle: Text('ID: ${township.id}'),
              );
            }).toList(),
          ],
        );
      },
    );
  }
}
