I am developing a mobile app using react native Expo. I used the React Navigation version 5.x and getting the following warnings:
web Compiled with warnings.

回答1:
Remove imports that are not being exported from the file.
From what I saw StackRouter, TabRouter and DrawerRouter follow the same pattern and have not exported imports that have the endings: ActionType, RouterOptions and NavigationState.
I don't know if the Expo leaves these imports for later when it includes them on account of the SDK or something that escapes my knowledge, I made the change here and my project continued to run normally without these Yellow Boxes.
node_modules/@react-navigation/routers/lib/module/index.js BEFORE:
import * as CommonActions from './CommonActions';
export { CommonActions };
export { default as BaseRouter } from './BaseRouter';
export { default as StackRouter, StackActions, StackActionType, StackRouterOptions, StackNavigationState } from './StackRouter';
export { default as TabRouter, TabActions, TabActionType, TabRouterOptions, TabNavigationState } from './TabRouter';
export { default as DrawerRouter, DrawerActions, DrawerActionType, DrawerRouterOptions, DrawerNavigationState } from './DrawerRouter';
export * from './types';
//# sourceMappingURL=index.js.map
node_modules/@react-navigation/routers/lib/module/index.js AFTER:
import * as CommonActions from './CommonActions';
export { CommonActions };
export { default as BaseRouter } from './BaseRouter';
export { default as StackRouter, StackActions } from './StackRouter';
export { default as TabRouter, TabActions } from './TabRouter';
export { default as DrawerRouter, DrawerActions } from './DrawerRouter';
export * from './types';
//# sourceMappingURL=index.js.map
