Had problem while using flutter toast dependency and dependencies like facebook_login. I followed these steps and resolved it:

1. First, u need to test whether these toast and shared preference dependencies are causing problems or some other dependencies cause the problem.
2. For testing that, u need to create a new seprate flutter project having the same flutter toast and shared preference dependency and check now if u r able to get toasts or not.
3. If u r getting toast so there is no problem with ur toast dependency.
4. The problem might be in ur one of the social media dependency.

In my case, I followed the above steps and found that problem was in facebook dependency. Finally, I found that I did not provide details of my app at facebook developer console. So implemented that and my app was fine.
