Hello!! Im working on a plugin that let's anyone to create their own Chathead with custom content (just like Messenger). Currently the plugin has the following functionalities:

PERMISSIONS ON FIRST RUN.

issue with button clicked to retrieve the tag of the button pressed from android into flutter.

Custom Views for Header, Body, Footer.

Customization of Notification Text.

Customization of Notification Icon.

Customization of Bubble Icon.

Customization of Close Icon.

Customization of Close Background Icon.

FloatyHead runs even when the app is killed.

Added documentation to all the classes used in DART and KOTLIN.

I hope that this can be helpful to more devs and maybe even create their own implementations or expand this plugin :)

this is the github-repo: https://github.com/Crdzbird/floaty_chathead

and pub.dev: https://pub.dev/packages/floaty_head/score

feel free to send any comment or if you wanna add your own feature to be included on the package :)
