Don't automatically close error snackbar

[thehamzarocks]

Let the error snackbars persist for two reasons:

1. The user gets more time to read them.
2. In the case of polling for data, if an error occurs, we don't want it to repeatedly open and close which would be annoying.

Right ow, this is set to close in 5 seconds. Do you propose to increase the time or keep it persistent till a user closes it in certain cases?

[thehamzarocks]

Hmm, we could keep it open so the user could see the error for as long as he wanted.
But in case things start working again, the open snackbar might be misleading

Good point. Maybe we could get the both of both worlds... The SnackBar stays till the user dismisses it, but it automatically goes away if the failed network call had succeeded...

We would need a mechanism to then identify if that endpoint which failed before had succeed... should be doable. This is a nice problem to solve. :p

Yes, this is the ideal way :)
