Describe what you expected to happen:
It shouldn't scroll to new position when I add new items to list, and should keep latest position where user was like maintainVisibleContentPosition on ios
Example code:
<FlatList
ref={(ref) => { this.chatFlatList = ref; }}
style={styles.flatList}
data={this.state.items}
renderItem={this._renderItem}
maintainVisibleContentPosition={{
minIndexForVisible: 0,
}}
/>
