Looking for android api handbook for c72

[Wratheus]

Hello, I'm working as a flutter developer, I can't find handbook with andorid API for this device, containing Strings with Intents and actions, to send messages between my flutter app and native-code barcode plugin.
I saw you did repo with RFID for this device but java code is JARed. maybe you could share handbook if you have one please?
I asked Chainway themself, but they provided full java doc with chineese comments for whole their scanners code, can't really find what I'm looking for..

I actually created a flutter version for C72 and tested to make sure it works
