Documentation
| Property | Type | Default | Description |
|-----------|---------------------|----------|--------------------------------------------|
| tabs
| {label: string, badge:string, badgeColor?: string, [string]: any}[]
| required
| You don't have to pass this prop directly to tabbar. Istead, it's automatically passed from ScrollableTabView
from tabLabel
of your page. In defaultTabbar it is used only to pass a label, but we use it to pass there information about badges. Example tabLabel={{label: "Page #4", badge: 8, badgeColor: 'violet'}}
. Also you can pass any data you need as it's used as Map
|
| underlineColor
| string
| "navy"
| Set a color for underline. You can use also transparent
to hide underline |
| underlineHeight
| number
| 2
| Set a height for underline |
| underlineBottomPosition
| number
| 0
| Set a bottom for underline |
| tabBarStyle
| Object
| {}
| Set styles to TabBar container |
| activeTabTextStyle
| Object
| {}
| Set styles to text in tabs while tab is active |
| tabBarTextStyle
| Object
| {}
| Set styles to text in tabs |
| tabBadgeColor
| string
| {}
| Set a common color for all badges. To set badgeColor individually use badgeColor
in tab
property |
| tabMargin
| number
| 20
| Set space between tabs |
Warning: It's better to avoid usage of styles which can change the size of your active tab. E.g. font-weight
, font-size
. Underline still work but not as good as you can expect.
