1、Flutter Plugins编译中的 exit code 各自代表什么情况
exit code 0 表示程序执行成功，正常退出
exit code 1 表示程序执行执行过程中遇到了某些问题或者错误，非正常退出
exit code -1 表示程序执行执行过程中遇到了某些问题或者错误，非正常退出
2、flutter_inappwebview 插件的使用
插件地址：
https://pub-web.flutter-io.cn/packages/flutter_inappwebview/install
Expanded(
child: InAppWebView(
initialUrlRequest: URLRequest(
url: Uri.parse(
"https://www.phonegap100.com/newscontent.php?aid=${widget.arguments["aid"]}")),
onProgressChanged: (controller, progress) {
print(progress / 100);
if (progress / 100 > 0.999) {
setState(() {
showLoading = true;
});
}
},
))
Android 注意事项
1、minSdkVersion 17
2、添加<uses-permission android:name="android.permission.INTERNET"/>
Ios注意事项
后端配置苹果支持的https证书
3、device_info_plus 插件获取设备信息
getDeviceInfo() async {
final deviceInfoPlugin = DeviceInfoPlugin();
final deviceInfo = await deviceInfoPlugin.deviceInfo;
final deviceInfoMap = deviceInfo.toMap();
var templist = deviceInfoMap.entries.map((e) {
return ListTile(
title: Text("${e.key}:${e.value}"),
);
}).toList();
setState(() {
list = templist;
});
}
4、connectivity_plus 检测网络
dynamic subscription;
String stateText = "检测中...";
@override
void initState() {
super.initState();
subscription = Connectivity()
.onConnectivityChanged
.listen((ConnectivityResult result) {
if (result == ConnectivityResult.wifi) {
setState(() {
stateText = "处于 wifi";
});
} else if (result == ConnectivityResult.bluetooth) {
setState(() {
stateText = "处于蓝牙";
});
} else if (result == ConnectivityResult.mobile) {
setState(() {
stateText = "处于手机网络";
});
} else {
setState(() {
stateText = "没有网络";
});
}
});
}
5、url_launcher 配置打开URL、拨打电话 、发送短信 、打开外部应用、打开高德地图

<action android:name="android.intent.action.VIEW" />
<data android:scheme="sms" />
</intent>
<!-- If your app checks for call support -->
<intent>
<action android:name="android.intent.action.VIEW" />
<data android:scheme="tel" />
</intent>
</queries>
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>
