We are a development agency building phenomenal apps.

Usage

1. Remember Int to store the current selection

var selectedIndex by remember { mutableStateOf(0) }

2. Pass your buttons to the AnimatedNavigationBar

AnimatedNavigationBar(selectedIndex = selectedIndex) {
   Button1()
   Button2()
   Button3()
}

Required parameters

selectedIndex - binding to the current index
content - buttons to display in the tabbar

Additional parameters

barColor - Color of the navigation bar itself
ballColor - Ball indicator color
cornerRadius - The corner radius to all corners applied to the navigation bar
ballAnimation - Ball animation with the animation curve, default value Parabolic(tween(300))

• Parabolic - Jump to the selected button following a parabolic arc
• Teleport - Disappear and quickly re-appear above selected tab
• Straight - Slide to the selected tab
  You can build your own animation, just implement the BallAnimation interface.

indentAnimation - Indent animation with the animation curve, default value is Height(tween(300))

• Height - Disappear by decreasing in height and quickly re-appear by increasing in height above the selected tab

  You can also build your own animation, just implement the IndentAnimation interface.

Built-in animatable tab buttons

This library has two built-in button types you can use out-of-the-box: DropletButton and WiggleButton, and a super custom ColorButton type in the Example project. Please feel free to use them in your projects or build your own buttons.
