Description

Imagine that we have a stateful react component and is about to creating a declaration file d.ts for the .js/.jsx file.

declare class StateCom extends React.Component<Props> {}
export default StateCom;

and error/warning occurs that: Component should be written as a pure function eslint(react/prefer-stateless-function)

How can we handle this since the component is a truly Component with state instead of a functional component?

Contributor guide

Research direction
Examine the rule logic for prefer stateless function and determine why it processes .d.ts files. Add a check to skip declaration files or modify the rule to ignore components declared as classes in .d.ts.
