url_launcher更新后，如何启动Google Maps URI？

Question

我已经更新了我的Flutter App软件包，包括url_launcher 6.0.20的软件包 6.1.2。

更新后，许多Android用户（API 30/31/32）报告说，由于错误，他们无法使用Google Map App启动导航（纬度和经度），

Webpage not available. 

Webpage not available
The webpage at intent://maps.app.goo.gl/?
link=https://www.google.com/maps/dir//45.8597077,.........
could not be loaded because:
net: ERR_UNKNOWN_URL_SCHEME

这是我的工作代码：我使用6.0 .20

final String gMapsUrl = 'https://www.google.com/maps/dir/api=1&destination=$latitude,$longitude&travelmode=driving';

if (Platform.isAndroid && await canLaunch(gMapsUrl)) {
  await launch(gMapsUrl);
}

，这是与6.1.2无法使用的，

 final String gMapsUrl = 'https://www.google.com/maps/dir/api=1&destination=$latitude,$longitude&travelmode=driving';

if (Platform.isAndroid && await canLaunchUrl(gMapsUri)) {
  await launchUrl(gMapsUri);
} 

它现在是启动Google Maps URL的正确方法，以启动InApp或Web浏览器导航而无需强迫用户使用Inapp还是Web导航？

Answer 1

这两个版本之间可能已经更改了一些默认值。
现在指定模式我解决了我的问题强迫在应用程序上打开：

await launchUrl(gMapsUri, mode: LaunchMode.externalApplication);

Answer 2

声明该应用程序要打开URL。

<intent>
  <action android:name="android.intent.action.VIEW" />
  <category android:name="android.intent.category.BROWSABLE" />
  <data android:scheme="https" />
