Issue
Always getting this error on a project without any reason for the moment could you help me on this.
Undefined name ‘ScaffoldMessenger’.
Try correcting the name to one that is defined, or defining the name.
Flutter version : 1.22.5 stable
Could you help me on this please ?
Solution
According to https://flutter.dev/docs/release/breaking-changes (at the moment), under Not yet released to stable, we see SnackBars managed by the ScaffoldMessenger. So, it’s not in 1.22… it’ll be in the next release.
