react native Flatlist renderItem not update
You might want to add the extraData prop to the flatlist:
<FlatList renderItem={this._renderItem} keyExtractor={ (item,index) => index.toString() } data={this.state.data} extraData={this.state}/>FlatList extraData:
A marker property for telling the list to re-render (since it implements PureComponent). If any of your renderItem, Header, Footer, etc. functions depend on anything outside of the data prop, stick it here and treat it immutably.
