Flutter华为云服务集成插件agconnect_core的使用

简介

agconnect_core 是一个用于集成华为云服务的 Flutter 插件。它允许开发者在 Flutter 应用中使用华为云服务的核心功能。

安装插件

首先，在你的 Flutter 项目的 pubspec.yaml 文件中添加依赖项：

dependencies:
  agconnect_core: ^1.2.0

然后运行以下命令以获取依赖项：

flutter pub get

使用示例

以下是一个完整的示例代码，展示了如何使用 agconnect_core 插件来调用一些核心功能。

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:agconnect_core/agconnect_core.dart';

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

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _log = '';
  late AGConnectOptions agConnectOptions;
  final optionsBuilder = AGConnectOptionsBuilder()
    ..productId = "productId"
    ..appId = "appId"
    ..cpId = "cpId"
    ..clientId = "clientId"
    ..clientSecret = "clientSecret"
    ..apiKey = "apiKey"
    ..routePolicy = AGCRoutePolicy.UNKNOWN
    ..packageName = "packageName";

  // 构建实例
  _buildInstance() async {
    agConnectOptions = AGConnectOptions(optionsBuilder);
    AGConnectInstance.instance
        .buildInstance(agConnectOptions)
        .then((value) {
    }).catchError((error) => print(error));
  }

  // 获取包名
  _getPackageName() async {
    AGConnectOptions(optionsBuilder)
        .getPackageName()
        .then((value) {
      setState(() {
        _log = 'getPackageName = ${value}';
        print(_log);
      });
    }).catchError((error) => print(error));
  }

  // 获取路由策略
  _getRoutePolicy() async {
    AGConnectOptions(optionsBuilder)
        .getRoutePolicy()
        .then((value) {
      setState(() {
        _log = 'getRoutePolicy = ${value}';
        print(_log);
      });
    }).catchError((error) => print(error));
  }

  // 获取字符串值
  _getString() async {
    AGConnectOptions(optionsBuilder)
        .getString("/client/app_id", "defValue")
        .then((value) {
      setState(() {
        _log = 'getString = ${value}';
        print(_log);
      });
    }).catchError((error) => print(error));
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Builder(builder: (BuildContext context) {
