[javascript] React Native - Image Require Module using Dynamic Names

As the React Native Documentation says, all your images sources needs to be loaded before compiling your bundle

So another way you can use dynamic images it's using a switch statement. Let's say you want to display a different avatar for a different character, you can do something like this:

class App extends Component {
  state = { avatar: "" }

  get avatarImage() {
    switch (this.state.avatar) {
      case "spiderman":
        return require('./spiderman.png');
      case "batman":
        return require('./batman.png');
      case "hulk":
        return require('./hulk.png');
      default:
        return require('./no-image.png');
    }
  }

  render() {
    return <Image source={this.avatarImage} />
  }
}

Also, remember if your image it's online you don't have any problems, you can do:

let superhero = "spiderman";

<Image source={{ uri: `https://some-website.online/${superhero}.png` }} />
