type 'String' is not a subtype of type 'int' - Error thrown when Major set on iBeacon selection

[tristanwilson111]

Hey there,

I've got my beacon detected with Generic UUID, Major and Minor settings in place. With iBeacon, it seems when I have any value (String, int, etc.) in the Major text area, this error is thrown. I am able to use iBeacon when Major is blank.

Stacktrace:

I'm still learning both Flutter and Dart, and tried to see if there were any mismatched variables, but saw none. This is not an issue for me as I am able to work around it, just figured I would make an issue in case it's something needing fixed.

This error was produced on a Google Pixel running the Android P Beta.

Can you show me code you're using to listen to iBeacons?
Thanks.

[tristanwilson111]

Code being used is your example application.

What happens if you change the datatype to String? I am studying your plugin and will try to contribute.

EDIT: It works for me when I changed the Datatype of "int" to "String"
