/**
 * FormData input type.
 *
 * `FormDataInput<T>` is a type for the input of the `FormData` request, casting
 * `File` property value type as an union of `File` and
 * {@link FormDataInput.IFileProps}, especially for the React Native
 * environment.
 *
 * You know what? In the React Native environment, `File` class is not
 * supported. Therefore, when composing a `FormData` request, you have to put
 * the URI address of the local filesystem with file name and content type that
 * is represented by the {@link FormDataInput.IFileProps} type.
 *
 * This `FormDataInput<T>` type is designed for that purpose. If the property
 * value type is a `File` class, it converts it to an union type of `File` and
 * {@link FormDataInput.IFileProps} type. Also, if the property value type is an
 * array of `File` class, it converts it to an array of union type of `File` and
 * {@link FormDataInput.IFileProps} type too.
 *
 * Before | After ----------|------------------------ `boolean` | `boolean`
 * `bigint` | `bigint` `number` | `number` `string` | `string` `File` | `File \|
 * IFileProps`
