flutter安卓下面網絡請求的問題

flutter默認在安卓下面是沒有打開爲網絡權限的，跟iOS一樣，需要配置網絡請求的權限。
在項目下面的android/app/src/profile的 AndroidManifest.xml添加如下代碼

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.graphqldemo">
    <!-- Flutter needs it to communicate with the running application
         to allow setting breakpoints, to provide hot reload, etc.
    -->
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
</manifest>
