Problem:
Hi TB team. To point the documentation is outdated about the last version of the Mobile App. Docu is up to 1.1.0, but the App is in its 1.2.0 version now. Thanks.

Proposed Solution:
Include in the 'Flutter ThingsBoard Mobile Application compatibility table' a new row for TB 3.7 and the 1.2.0 app

Page to Update:
https://thingsboard.io/docs/mobile/getting-started/#step-2-get-app-source-code

3.7
