Backstack entry's view state is never saved on rotation about flow HOT 8 CLOSED

↑ Here is an example of solving issue for rotation only situation (when backstack stays the same instance).

from flow.

Please, could someone tell me why ActivityFlowSupport#getBackstackToSave(Backstack backstack) creates a copy of backstack with dropped viewstates? This is key to problem of overall persistance (e.g. activity was destroyed and user goes back to app again)

↑ Fix for graceful backstack's viewstates persistance. Don't know if it's dirty for current code model, so punish hard, ready to take it further

PTAL at https://github.com/square/flow/pull/72/files

@rjrjr Sorry, I found no solution of this problem in #72, because:

• ActivityFlowSupport#getBackstackToSave still ignores current viewstates of backstack entries;
• flow support doesn't do snapshot of viewstate of current path before getBackstackToSave called, so I suppose e.g. EditText text will still be lost on rotation.

Yup, rotation is definitely broken. Still not sure that this is the way to fix it though, looking.

Yep. Thanks for the catch, and for the patches. I've made some slightly different fixes in #75.

Thanks, looks great.
