How can I pass data to the first Fragment whilst using the Navigation Architecture?

I'm trying to pass a bundle of object instances down from my main activity to the first fragment in a chain of other fragments using the NavHostFragment. I've tried all sorts but the bundle always seems to be null once it reaches the first fragment.



Here's how I'm initiating the NavHostFragment (frameContainer is a Frame Container element in my layout xml)



NavHostFragment navHost = NavHostFragment.create(R.navigation.claim_nav_graph);

getSupportFragmentManager().beginTransaction()

        .replace(R.id.frameContainer, navHost)

        .setPrimaryNavigationFragment(navHost)

        .commit();


The documentation says there are 2 different .create functions, one of them you can pass a second arguments to as a bundle, but Android Studio doesn't allow me to use this version.



Does anyone have any ideas?



Thanks in advance!

But the keyboard doesn't show when I tap the TextFormField at the first time. Then I try to input some letter from physical keyboard, the widget is rebuilt. Like this: login screen Nothing to be log when I run flutter run --verbose, so I logged manually. Every tapping on field, the widget called dispose -> init -> build.

It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
