Dynamic resize not working

[victorlsn]

I have a view which contains multiple textviews which will be "part of the ticket", but when I increase one of the textviews number of lines from 1 to 2, it works on the preview, but in real-time execution the resize doesn't work.

I have the same issue.

@vipulasri sir

I have made a minor change to support the dynamic size ticket view. Please refer to the screenshot.

I am using two ticket views and thus will have the advantage of changing ticket colors as well. Let me if I can share make a PR for the same.

[vipulasri]

@mwshubham seems like a performance heavy solution. Can you please elaborate on the actual issue you are facing?

[mwshubham]

It is not a performance heavy solution but rather not useful for many as it is a specific use case. But we can have a similar feature to have different top and bottom colors. The reason why it is not performance heavy is that I am achieving the same via special cases when scallop percentage is either 100 (for top ticket) and 0 for the bottom ticket. In the former case, I am not drawing the bottom line and arcs and top line and arcs for later.

@mwshubham can you show me some screenshots for the same? I mean the desired result
