DrawApp
Sample Flutter Drawing App which allows the user to draw onto the canvas along with color picker and brush thickness slider.
All code free to use and located within /lib.
Special thanks to stackoverflow user Andrey Turkovsky for helping out with color per drawn line issue.
Merged with domesticmouse/drawapp which added cool stuff like BLoC pattern and tests. Go here if you want a version without these which might be easily to understand for those without BLoC knowledge.
