Introduction

Tabs component supporting RN side and web side
Provide an underscore to follow the selected tab, and adapt to the width or height of its tab
You can pass the Animated animation value listener to do the motion synchronization. If you don't pass it, you can also provide the animation value. You can set the duration.
You can pass the relevant style to determine the container style according to your needs.
RN and Web support adaptive scrolling, scrolling when the width of the tab exceeds the container, and setting the corresponding scroll style, otherwise the default use of justifyContent: space-between style full container, you can change the default style by setting scrollViewStyle
You can use the width/height in the underlineStyle to give the underline a fixed size. If you exceed the container size, you can ignore it. You can set the isAutoSize to restore the automatic size when the tabBar is scrollable.

Note

based on react-native-underline-tabbar The RN component library draws on the animation of the underlined part. Based on this, the scrolling and onLayout code is optimized, and the web component is developed. If you are interested, you can go and see it.
Tabs view synchronization animation can be done with react-scroll-paged-view

- [x] Provide web-side version, unified props, consistent with RN
- [x] Provides its own animation, when no animation values are passed in
- [x] Add automatic scrolling positioning configuration
- [ ] Fix the problem of switching animation violations again after manual scrolling
- [x] Provide friendly tabbed form without scrolling
- [ ] More props configuration
- [x] Add a configuration that shows tabs vertically
- [x] Provides settings related to the fixed size of the slide line
