Hey, @quozl @chimosky
Can you review this PR i have added a clear button and refactor the code for better understanding

[ravjot07]

@quozl can you review this pr

[chimosky]

Are these used here?

See #15 to make sure you've addressed the concerns listed there, reviewed, not tested.

The code refactoring shouldn't be in the same commit as the clear button change, keep both separate as it's easier to review that way.

yes i have addressed the concerns listed in #15.... mainly they discussed about position of the button and its icon visibility and its functioning about deleting only the drawing rather than whole canvas...... i have covered all of that

@chimosky are there any more changes or suggestion or we should merge this PR

Would be great to have better commit messages than "Minor Updates", see making commits.

I'll test this once I can.
