Package used for Permissions

permission_handler: ^10.2.0

Let me know any other details are required

I have tried adding permissions manually from the device. Still web view in android is not getting the permission

Answer 1

I have same problem. I've granted microphone permission to the application after adding AndroidManifest.xml necessery code but webView doesn't include it.

---

if (await Permission.microphone.request().isGranted) {
  // Either the permission was already granted before or the user just granted it.
} else {
 // You can request multiple permissions at once.
Map<Permission, PermissionStatus> statuses = await 
  [Permission.microphone].request();
}
print(statuses[Permission.location]);
