首先转到 AndroidManifest.xml。它可以在/android/app/src/main 中找到。

然后只需添加到标签android:usesCleartextTraffic="true"下即可。<application

您的 AndroidManifest.xml 应如下所示

<application
        android:name="io.flutter.app.FlutterApplication"
        android:label="shafa_doctor"
        android:requestLegacyExternalStorage="true"
        android:usesCleartextTraffic="true" //just add this line only
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
