Manage you project Routes. Create nested routes. Simply navigation without context to your pages. Change only one sub widget in your page when navigating to new route.
@Zazo032 first of all I'm sorry for the late reply.
You run 'flutter create .' command in the example folder and you will have the project for Android and ios.
It's not bundled in the repository, so trying to run the example app in Android/iOS will require running
flutter create .
to generate the folders.
