這篇文章主要講解了“在Flutter工程基礎上怎么集成及運行小程序”,文中的講解內(nèi)容簡單清晰,易于學習與理解,下面請大家跟著小編的思路慢慢深入,一起來研究和學習“在Flutter工程基礎上怎么集成及運行小程序”吧!
在張掖等地區(qū),都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局,加強發(fā)展的系統(tǒng)性、市場前瞻性、產(chǎn)品創(chuàng)新能力,以專注、極致的服務理念,為客戶提供網(wǎng)站制作、成都網(wǎng)站制作 網(wǎng)站設計制作按需定制制作,公司網(wǎng)站建設,企業(yè)網(wǎng)站建設,品牌網(wǎng)站設計,成都全網(wǎng)營銷推廣,外貿(mào)網(wǎng)站制作,張掖網(wǎng)站建設費用合理。本文將使用 Flutter1.12.hotfix8 穩(wěn)定版作為開發(fā)環(huán)境。
下載 FlutterSDK
配置 PATH 環(huán)境路徑
flutter doctor 檢查環(huán)境
flutter create --template=app --org=com.finogeeks.flutter --project-name=mini_flutter -i objc -a java ./mini_flutte
執(zhí)行以上命令后,正常將會提示以下信息
All done![?] Flutter: is fully installed. (Channel stable, v1.12.13+hotfix.8, on Mac OS X 10.15.3 19D76, locale zh-Hans-CN)[?] Android toolchain - develop for Android devices: is fully installed. (Android SDK version 29.0.3)[?] Xcode - develop for iOS and macOS: is fully installed. (Xcode 11.3.1)[?] Android Studio: is fully installed. (version 3.6)[!] IntelliJ IDEA Ultimate Edition: is partially installed; more components are available. (version 2019.3.3)[?] VS Code: is fully installed. (version 1.42.1)[!] Proxy Configuration: is partially installed; more components are available.[?] Connected device: is fully installed. (1 available)Run "flutter doctor" for information about installing additional components.In order to run your application, type: $ cd mini_flutte $ flutter run Your application code is in mini_flutter/lib/main.dart.
注意!flutter 需要依賴本地安裝對應的 iOS,Android 開發(fā)工具,即需要安裝 Xcode 和 AndroidStudio。具體安裝使用方法這里不贅述。
這里我們用 VSCode+Xcode 作為開發(fā)組合環(huán)境,如果要正常調(diào)試需要確保以下三個檢查項目是正常的。
[?] Xcode - develop for iOS and macOS: is fully installed. (Xcode 11.3.1)
Flutter: is fully installed. (Channel stable, v1.12.13+hotfix.8, on Mac OS X 10.15.3 19D76, locale zh-Hans-CN)
VS Code: is fully installed. (version 1.42.1)
[!] Proxy Configuration: is partially installed; more components are available.
這里我們采用凡泰免費社區(qū)版的小程序解析引擎,只需要 10 行代碼量不到即可完成小程序集成。
引入小程序引擎插件。在 pubspec.yaml 文件中引入小程序 Flutter 插件
mop: ^0.2.0
2.在 main.dart 文件中增加以下小程序引擎初始化方法。Mop.instance.initialize這里需要用到 sdkkey 和 secret??梢灾苯釉?https://mp.finogeeks.com免費注冊獲取。注冊使用方法可以參考 接入指引
// Platform messages are asynchronous, so we initialize in an async method. Futureinit() async { if (Platform.isIOS) { final res = await Mop.instance.initialize( '22LyZEib0gLTQdU3MUauAYEY1h9s9YXzmGuSgQrin7UA', '9e05fa0015d7dbfa', apiServer: 'https://mp.finogeeks.com', apiPrefix: '/api/v1/mop'); print(res); } else if (Platform.isAndroid) { final res = await Mop.instance.initialize( '22LyZEib0gLTQdU3MUauAYEY1h9s9YXzmGuSgQrin7UA', '9e05fa0015d7dbfa', apiServer: 'https://mp.finogeeks.com', apiPrefix: '/api/v1/mop'); print(res); } if (!mounted) return; }
3、在主界面上增加三個按鈕來打開小程序
Center( child: Container( padding: EdgeInsets.only( top: 20, ), child: Column( children:[ Container( width: 140, decoration: BoxDecoration( borderRadius: BorderRadius.all(Radius.circular(5)), gradient: LinearGradient( colors: const [Color(0xFF12767e), Color(0xFF0dabb8)], stops: const [0.0, 1.0], begin: Alignment.topCenter, end: Alignment.bottomCenter, ), ), child: FlatButton( onPressed: () { Mop.instance.openApplet('5e3c147a188211000141e9b1', path: 'pages/index/index', query: ''); }, child: Text( '打開畫圖小程序', style: TextStyle(color: Colors.white), ), ), ), SizedBox(height: 30), Container( width: 140, decoration: BoxDecoration( borderRadius: BorderRadius.all(Radius.circular(5)), gradient: LinearGradient( colors: const [Color(0xFF12767e), Color(0xFF0dabb8)], stops: const [0.0, 1.0], begin: Alignment.topCenter, end: Alignment.bottomCenter, ), ), child: FlatButton( onPressed: () { Mop.instance.openApplet('5e4d123647edd60001055df1'); }, child: Text( '打開官方小程序', style: TextStyle(color: Colors.white), ), ), ), SizedBox(height: 30), Container( width: 140, decoration: BoxDecoration( borderRadius: BorderRadius.all(Radius.circular(5)), gradient: LinearGradient( colors: const [Color(0xFF12767e), Color(0xFF0dabb8)], stops: const [0.0, 1.0], begin: Alignment.topCenter, end: Alignment.bottomCenter, ), ), child: FlatButton( onPressed: () { Mop.instance.openApplet('5e637a18cbfae4000170fa7a'); }, child: Text( '我的對賬單', style: TextStyle(color: Colors.white), ), ), ), ], ), ), )
4、運行 Flutter 程序
在代碼根目錄執(zhí)行 flutter devices 查看本機安裝的模擬器。
執(zhí)行 flutter run --debug 運行示例,運行效果之如本文最前面所展示的圖示。
