深层链接不会每次都打开 flutter 应用程序

Question

我尝试在我的 flutter 应用程序中实现深度链接。现在，如果我通过 Discord 发送并单击“访问网站”，深层链接就会起作用并打开应用程序。但当我通过 Instagram 发送链接或在二维码中使用它时，它只会在浏览器中打开链接。

我正在运行 Android 12 的三星 S10 上测试该应用程序。除了 Discord 之外，它始终打开三星浏览器而不是应用程序。

AndroidManifest.xml：

<manifest xmlns:android="http://schemas.android.com/apk/res/android">

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

    <application
        android:label="example_project"

应用程序中的使用：

onPressed: () async {
                    final result = await Share.share(
                        'Tritt meiner Party auf Example bei: https://example-app.at/joinParty/${id}',
                        subject: 'Tritt meiner Party bei');

                    if (result.status == ShareResultStatus.success) {
                      Navigator.pop(context);
                    }
                  },

我认为你在这里遗漏了一些重要的东西。 Android 需要确保该域属于您。因此，您需要通过位于

.well-known/assetlinks.json

的主机提供 assetlinks.json。

 [{
    "relation": ["delegate_permission/common.handle_all_urls"],
    "target": 
    {
     "namespace": "android_app",
     "package_name": "com.example",
     "sha256_cert_fingerprints":["14:6D:E9:83:C5:73:06:50:D8:EE:B9:95:2F:34:FC:64:16:A0:83:42:E6:1D:BE:A8:8A:04:96:B2:3F:CF:44:E5"]
    }
}]
