Values for NavigationParams are defined as strings (is it on purpose?)

[juhasuni]

TypeDefinition.js defines NavigationParams as a map where each value (parameter) must be a string.

export type NavigationParams = { [key: string]: string, };

Yet, in the same file there's a documented example, where the value is an int.

/**
   * Params passed to this route when navigating to it,
   * e.g. `{ car_id: 123 }` in a route that displays a car.
*/

To me it looks like NavigationParams type definition is wrong, but I couldn't be sure, since you may have thought about URL routing, where each parameter must be string.

To me, the type could be:

export type NavigationParams = {
  [key: string]: mixed,
};
