为什么在安装app-release.apk时flutter应用程序无法连接到Internet?但在调试模式下正常 [英] why flutter application can't connect to internet when install app-release.apk? but normal in debug mode

问题描述

在调试模式下，一切看起来都不错，请从我的API获取响应和数据列表.但是，在构建app-release.apk并安装到手机上之后，它显示没有互联网连接

when in debug mode everything looks good, get response and lists of data from my API. But after I build app-release.apk and install to my phone, it shows no internet connection

这是我的代码

ScopedModelDescendant<ReportPosViewModel>(
  builder: (context, child, model) {
    return FutureBuilder<List<Invoice>>(
      future: model.invoices,
      builder: (_,
          AsyncSnapshot<List<Invoice>> snapshot) {
        switch (snapshot.connectionState) {
          case ConnectionState.none:
          case ConnectionState.active:
          case ConnectionState.waiting:
            return Center(
                child:
                    const CircularProgressIndicator());
          case ConnectionState.done:
            if (snapshot.hasData) {
              //something todo
            } else if (snapshot.hasError) {
              return NoInternetConnection(
                action: () async {
                  await model.setInvoice();
                  await getData();
                },
              );
            }
        }
      },
    );
  },
),

推荐答案

在android/app/src/main的AndroidManifest.xml文件中，您需要在<manifest标记中添加此权限.

In the AndroidManifest.xml file located at android/app/src/main you need to add this permission in <manifest tag.

<uses-permission android:name="android.permission.INTERNET"/>
