"Type" in React Native

What's does type Props = {}; mean in React Native project?

It's used in extends Component<Props>

Is it flow? But I don't see flow in dependecies.

Visual Studio Code says it's an error. But everything compiles without problems.

It is a TypeScript code. extends Component means that your class/ component props will have to conform with that Props type.

For example,

type Props = {
  name: string
}

class Example extends Component<Props> {
...
}

Later, when you want to use that component, you should put the props like this

<Example name='test'/>

If not, TypeScript will give you a compile error.
