Showcase
Usage
drawTextOnPath function is used to draw text along path.
canvas.drawTextOnPath(text, path);
drawOnPath function is used to draw pattern along path. index can be used to draw different element at different position based on some logic. Use canvas to draw anything at position. The next position is calculated based on spacing provided.
spacing should be greater than 0. Ideally spacing is the sum of one element width and spacing between two elements (spacing between starting points of two consecutive elements)
Note: If the text (for given textStyle) is larger than the path, then it will clip extra text.
