I've already sent a PR which awaits a review.

@nicolas-raoul @ShridharGoel I suggest using CSnackBar Library for this task :)

[nicolas-raoul]

@neslihanturan Do you think this is a good idea, actually? If yes, Rishav can work on it.

@madhurgupta10 Is a library really needed? The PR #2389 does not seem to use any.

[madhurgupta10]

@nicolas-raoul External library not needed for this task. Also, we should not be replacing every single Toast with Snackbar

[shankarpriyank]

@nicolas-raoul I guess I will be able to fix the failing tests in #4920.
Can you please assign me this issue?

Hello,
I would like to work on this issue.

Proposed Solution
I would be utilising the util class of snackbar which we have in ViewUtil and replace the Toasts with Snackbar this will allow to make code dry and readable.

Can I get assigned to it? @nicolas-raoul

[nicolas-raoul]

@shankarpriyank I unassign for now, but if you are you still working on this, please let us know. If no answer, someone else may be assigned to it. Thanks a lot. :-)
