+Do you like this library and would you like to support it? [Due to popular demand we've created a money-pool](https://github.com/IjzerenHein/react-navigation-shared-element/issues/14) to implement support for [@react-navigation/native-stack](https://reactnavigation.org/docs/native-stack-navigator/). All funds will be used to implement this feature as well as for continued development this library and [react-native-shared-element](https://github.com/IjzerenHein/react-native-shared-element).
