[ BUG ] : The next slide button and finish button have the same styles

[rick427]

Plugin name
Flutter Onboarding Slider

Describe the bug
The finish button style and the next slide styles are the same which makes styling both buttons differently difficult

To Reproduce
Steps to reproduce the behavior:

1. Set a border radius of 100 on the finish button style

Expected behavior
The next slide button should have a different style property than the finish button style. So if set a border radius of 100 (i.e. make the next slide button circular) the finish button is also circular (i.e. I want the finish button to have sharper edges). In short I expect 2 different styles for both buttons similar to what was shown in the docs here
