Flutter集成特定服务插件flutter_naurt_sdk的使用

Naurt’s Official flutter plugin

flutter_naurt_sdk 是 Naurt 官方提供的 Flutter 插件。它允许开发者在 Flutter 应用中集成 Naurt 的服务功能。

使用步骤

以下是一个完整的示例，展示如何在 Flutter 应用中集成 flutter_naurt_sdk 插件。

1. 添加依赖

首先，在项目的 pubspec.yaml 文件中添加 flutter_naurt_sdk 和 permission_handler 依赖：

dependencies:
  flutter:
    sdk: flutter
  flutter_naurt_sdk: ^版本号 # 替换为最新版本号
  permission_handler: ^版本号 # 替换为最新版本号

然后运行以下命令安装依赖：

flutter pub get

2. 初始化插件

在应用的入口文件中初始化 flutter_naurt_sdk，并请求必要的权限。

import 'dart:io';
import 'dart:isolate';

import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:flutter_naurt_sdk/flutter_naurt_sdk.dart';

import 'package:permission_handler/permission_handler.dart';

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

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  bool isInitialised = false;
  bool isRunning = false;
  bool isValidated = false;

  [@override](/user/override)
  void initState() {
    super.initState();
    initPlatformState();
  }

  Future<void> getPermissions() async {
    if (Platform.isAndroid) {
      Map<Permission, PermissionStatus> statuses =
          await [Permission.location, Permission.phone].request();
    } else if (Platform.isIOS) {
      Map<Permission, PermissionStatus> statuses = await [
        Permission.location,
        Permission.storage,
        Permission.sensors,
        Permission.phone
      ].request();
    }
  }

  // 平台消息是异步的，因此我们在异步方法中进行初始化。
  Future<void> initPlatformState() async {
    await getPermissions();

    // 可能会抛出 PlatformException，我们使用 try/catch 来捕获异常。
    try {
      final naurt = Naurt.shared;

      // 监听位置更新事件
      naurt.onLocationChanged.listen((location) {
        print('onLocationChanged: ${location.toString()}');
      });

      // 监听初始化状态
      naurt.onInitialised = (bool isInitialisedIn) {
        setState(() {
          isInitialised = isInitialisedIn;
        });
      };

      // 监听验证状态
      naurt.onValidation = (bool isValid) {
        setState(() {
          isValidated = isValid;
        });
      };

      // 监听运行状态
      naurt.onRunning = (bool isRunning) {
        setState(() {
          this.isRunning = isRunning;
        });
      };

      // 初始化插件
      isInitialised = await naurt.initialise(apiKey: '', precision: 6);
    } on PlatformException {
      isInitialised = false;
    }

    // 如果小部件从树中移除时异步平台消息仍在飞行中，则丢弃回复而不是调用 setState 更新非存在的外观。
    if (!mounted) return;
    setState(() {});
  }
