Error NoSuchMethodError in the example

Error NoSuchMethodError in the example

karavanov opened this issue 4 years ago · comments

When building any example, an error is written in the debag (I attach the log below). What is the reason for it and how to fix it? When scrolling the list, it is repeated.

Flutter 1.17.0
Dart 2.8.1
