Features

• Easy to use and easy to read code
• React-Native Javascript library built on top of FlatList.

Usecases

• Dynamic tab data that can be populated by code (typically tabs are determined by an API call)
• Ability to select any index (and just the zeroth index) as the default index.

How to use

Simply install by running yarn add react-native-dynamic-tab-view

Use it by

import DynamicTabView from 'react-native-dynamic-tab-view';
 <DynamicTabView
        data={dataSource}
        renderTab={renderTab}
        onChangeTab={onChangeTab}
        defaultIndex={defaultIndex}
        containerStyle={styles.container}
        headerBackgroundColor={'white'}
        headerUnderlayColor={'blue'}
      />

Here data is of the format

[
   { title: 'Tab1', key: 'item1' },
   { title: 'Tab2', key: 'item2' },
   { title: 'Tab3', key: 'item3' },
]

title sets the tab title key is used internally by React. It can be any unique string

FAQs

Why are you building another TabView library?

At present, there are two tabView libraries that are out there

• react-native-scrollable-tab-view
• react-native-tab-view I have used both of them and I had multitude of issues with them.
• react-native-scrollable-tab-view
  • Doesn't have proper maintainence. Last update was back in October. There are lot of open PRs.
  • Code is bloated and I tried fixing issues, but couldn't navigate my way through
  • Uses different code for Android and iOS and therefore I had issues like some view works with Android well and not with iOS and viceverca
• react-native-tab-view
  • Uses different code for Android and iOS
  • Couldn't get default page selected working with this.
  • Built and works well for static views (dynamic tabs doesn't work very well with Android)

How's react-native-dynamic-tab-view different?

• Uses same code for Android and iOS
• More importantly, uses FlatList for creating the tabViews
• Easy to read code
