如何在颤振中使用android_intent_plus打开pdf？

Question

I have a .pdf on download android folder, and I want to open it with flutter.

I tried:

final AndroidIntent intent = AndroidIntent(
                  action: 'android.os.Intent.ACTION_VIEW', //android.os.Intent.ACTION_VIEW  action_view
                  data: Uri.encodeFull("/storage/emulated/0/Download/myfile.pdf"), // content:// file://
                  //type: "application/*",
              flags: [
                Flag.FLAG_GRANT_READ_URI_PERMISSION,
                Flag.FLAG_GRANT_PERSISTABLE_URI_PERMISSION,
                Flag.FLAG_ACTIVITY_NEW_TASK
              ]);
              intent.launch();

But I get the following error:

V/IntentSender( 8997): Sending intent Intent { act=android.os.Intent.ACTION_VIEW dat=/storage/emulated/0/Download/myfile.pdf flg=0x10000041 (has extras) }

try this
import 'package:open_file/open_file.dart';

OpenFile.open("/sdcard/example.pdf");
