您可以检查谷歌Play Store应用程序是否已安装，如果是这种情况，您可以使用“market://”协议。

final String my_package_name = "........."  // <- HERE YOUR PACKAGE NAME!!
String url = "";

try {
    //Check whether Google Play store is installed or not:
    this.getPackageManager().getPackageInfo("com.android.vending", 0);

    url = "market://details?id=" + my_package_name;
} catch ( final Exception e ) {
    url = "https://play.google.com/store/apps/details?id=" + my_package_name;
}


//Open the app page in Google Play store:
final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
startActivity(intent);

由于官方文档使用https://而不是market://，这结合了Eric和M3-n50的答案和代码重用(不要重复你自己):

Intent intent = new Intent(Intent.ACTION_VIEW)
    .setData(Uri.parse("https://play.google.com/store/apps/details?id=" + getPackageName()));
try {
    startActivity(new Intent(intent)
                  .setPackage("com.android.vending"));
} catch (android.content.ActivityNotFoundException exception) {
    startActivity(intent);
}

如果GPlay应用程序存在，它会尝试打开GPlay应用程序，然后退回到默认状态。

对于费率应用:重定向到播放商店。 在Flutter中，你可以通过这样的平台通道进行操作

颤振部分:

 static const platform = const MethodChannel('rateApp');   // initialize 

onTap:平台。invokeMethod('urls'， {'android_id': 'com.xyz'})，

现在Android原生部分(Java):

private static final String RATEAPP = "rateApp";  // initialize variable

//现在在ConfigureFlutterEngine函数中:

        new MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), RATEAPP)
            .setMethodCallHandler(
                    (call, result) -> {               
                        if (call.method.equals("urls") && call.hasArgument("android_id")) {
                            String id = call.argument("android_id").toString();
                          
                            try {
                                startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("$uri" + id)));
                            } catch (android.content.ActivityNotFoundException anfe) {
                                startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + id)));
                            }
                            result.success("Done");
                        } else {
                            result.notImplemented();
                        }
                    }
            );

使用

打开出版商配置文件

@OnClick (R.id.ll_more_apps) 公共无效showMoreApps() { openPlayStore(true，“Hitesh Sahu”); ｝

在PlayStore上打开应用页面

@OnClick (R.id.ll_rate_this_app) 公共无效openAppInPlayStore() { openPlayStore(假," "); ｝
