a simulation of the trigonometric circle in flutter using custom paint for the first time
this app gives you the angle from the coordinates that you are pressing
the biggest challenge was to convert screen coordinates to angles , also it was pretty amazing to work with radians in every single function
I can turn this code into :
- Circular value displayer
- Circular slider
- detect the interaction direction (positive or negative) to change the angle sign
- select from a given range of values
