feat: New Feature Document Scanner

[bensonarafat]

Document Scanner feature based the new feature request #581

Key point to note:

• Low binary size impact (all ML models and large resources are downloaded centrally in Google Play services).
• No camera permission is required - the document scanner leverages the Google Play services' camera permission, and users are in control of which files to share back with your app.

Document Scanner is currently in Beta, and not currently available for iOS (I will stay updated and update this feature when available)

@fbernaly
The link job failed because, the package google_mlkit_document_scanner is not found in pub_spec. should i just use relative path instead ?

[fbernaly]

use path to pass it, and also make sure the job is added to this file:

https://github.com/flutter-ml/google_ml_kit_flutter/blob/develop/.github/workflows/flutter.yml

they are arrange in alphabetical order.

Yeah, i finally got it.
Thanks @fbernaly

Update:
@fbernaly all link now pass.

Follow the same design we have for the other plugins. You should have 2 files: DocumentScanner.java and GoogleMlKitDocumentScannerPlugin.java

[bensonarafat]

@fbernaly
Yeah! About that.
Separating the file won't work.
I did that initially, but we need to have the FlutterPlugin and ActivityAware on the same abstract class for the onAttachedToActivity to work for some reason. I spent sometime on it.

@bensonarafat : I have more comments.

My comment on separating the class

Name of this file should be:
GoogleMlKitDocumentScannerPlugin.h

[bensonarafat]

[fbernaly]

Name of this file should be:
GoogleMlKitDocumentScannerPlugin.m
