Description

maximumTrackTintColor is not working as expected on Android. The colour has a low opacity. e.g. "red" will appear as very light red. This problem is not happening on iOS; it's only an issue on Android.

Hello @paule89123!
Yes, this behavior is already reported in #84.
This is caused by the way the SeekBar is implemented natively by Android that this component library is based on. Because of that, this is not that straightforward to "fix" but will require a bit of changing the approach that I still have on the back of my head to happen.
Let me close this issue as a duplicate, please, but you can track the progress in the original issue.
Thank you!
