问题 I'm making a country picker with flags. The country names and flag image name is coming from database, like this (sample): dataSource: [ { id: 1, name: "Afghanistan", image: '../assets/flags/af.png' }, { id: 2, name: "Bahrain", image: '../assets/flags/ba.png' }, { id: 3, name: "Canada", image: '../assets/flags/ca.png' }] Then I send that dataSource to my component <CountryPickerFlags dataSource={this.state.dataSource} /> Then in the component FlatList (renderItem) I do: _renderItemListValues

问题 We have many React Native <Image> components rendering per screen and are witnessing performance issues due to many simultaneous http requests. Opening and closing a connection is expensive, and having too many simultaneous connections can hit limitations that cause timeouts. HTTP/2 features multiplexing, allowing multiple requests and response messages between the client and server to be in flight at the same time over a single connection, instead of multiple connections, which improves page

I see many mobile apps having a feature that user can draw a square to indicate something to tag on the image.

Any idea or suggestion will be highly appreciated! This is an example below You can use React Native ART library
