(could not find package fluttery_seekbar at https://pub.dartlang.org), version solving failed.

dose any one know how to fix this

Answer 1

Package was removed. More info here: https://github.com/dart-lang/pub-dev/issues/2853

Still some apps depend on it: https://libraries.io/pub/fluttery_seekbar

You can still download copy of it here: https://github.com/ganeshbehera/fluttery_seekbar/blob/b60704358fd27ae2f8ac41f8e29d87454d9103dc/fluttery_seekbar-master.zip

How to install it manually is here: https://github.com/flutter/flutter/issues/15817 (add version number to folder name, in the same way as other folder are named)

However you will also need fluttery 0.0.8 package which I was not able to find

Answer 2

try to resolve by running

flutter upgrade
flutter pub cache repair
