Answer 1

i found this issue issue TL:DR here is a summary

It looks like your local engine build flutter/engine and framework + tool flutter/flutter are out of sync: You're using an engine from when after SemanticsFlag.isLink was added, but a framework/tool from before it rolled into the framework.

You need to ensure that you're using compatible engines and frameworks. In this case, you need to either update flutter/flutter to a newer version or roll back flutter/engine to an older version.42356

This error also occurs due to Plugin / Packages incompatibility. There must be some packages which is upgraded to new version in your pubsec.yaml file and you are still using old version/ deprecated methods of it.

Thus you need to replace all deprecated methods with new.
