在 Flutter 中使用 URL Launcher 时出错

Question

onTap: () async {
  final url = products[index].url;

  if (!await canLaunch(url)) {
    await launch(url);
  } else {
    throw 'Could not launch $url';
  }

Error:

I/UrlLauncher(20613): component name for https://www.crucial.in/products/memory/desktop-dram is {com.android.chrome/com.google.android.apps.chrome.IntentDispatcher}
E/flutter (20613): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Could not launch https://www.crucial.in/products/memory/desktop-dram

Add this to your android manifest file:

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

And use this:

Future<void>_launchURL(String link) async {
  if (await canLaunchUrl(Uri.parse(link))) {
    await launchUrl(Uri.parse(link));
  } else {
    throw 'Could not launch $link';
  }
}

Works for me
