Conditional Navigation and Nested Graph Example

[IvanToplak]

General idea is to add more realistic flow to this app.
My suggestion is to add:

• Splash screen which contains rocket logo on a background,
• Login screen with welcome message and login button which calls Firebase UI flow,
• Nested graph representing main flow,
• Nested graph representing auth flow.

I've noticed that activity_main.xml has CollapsingToolbarLayout which means it will be shown on every fragment, which is usually not what we want (e.g. SplashFragment, LoginFragment, PhotoFragment and MapsFragment don't need to have toolbar at all). It would be better to move CollapsingToolbarLayout to fragment_main.xml.
NestedScrollView is a parent of FragmentContainerView. Scrolling behavior is also something that should be decided per each fragment.

@brimanning @julianfalcionelli what do you think?
I would need Rocket logo in vector graphic + the background image or Lottie animation for the splash screen. Who can provide these resources?

[brimanning]

Yeah, that sounds good to me. It probably applies to 95% of our apps, so I'd say go for it. Here's an SVG logo for you, hopefully it converts to a vector drawable easy enough.

Actually, here's a better logo to use: rocketinsights_logo_mark.svg.zip.

Nice. I can use this one with blue background.
