I want a basic starter configs/scripts for and Android text widget via Termux

I am looking for a skilled freelancer to help me with my project. I need the freelancer to create a basic starter configs/scripts for an Android text widget via Termux. I am asking for the configs/scripts to have basic text display only. Furthermore, I would like the scripts to be written in Bash. The sought after solution for this project should result in configs/scripts as needed for me to get started.

I have all the knowledge to engineer comprehensive bash scripts.
I'm looking to shortcut the time it's gonna take to research the Termux/widget/android/gui API's.

What I want is the basic Termux coding/configs/script to allow me to
1. whatever it takes to make Termux have Widget on the Android home screen
2. have a bash script running, which will output two different lines of text.
3. The android widget will show text "test line 1" by default.
4. if I tap on the android/termux widget, it will swap to other line of text "test line 2"
5. if I tap on widget again it will swap back to "test line 1"
6. as i continue tapping, it will continue rotating between "test line 1" and "test line 2"

With that sort of basic framework, I'll be able to figure out what i need from there...
