title: Flutter issue - Flutter_driver from sdk depends on file 5.0.6 and flutter_gallery depends on file 5.0.7

  <p><code>Because every version of flutter_driver from sdk depends on file 5.0.6 and flutter_gallery depends on file 5.0.7, flutter_driver from sdk is forbidden.
  So, because flutter_gallery depends on flutter_driver any from sdk, version solving failed.
  pub upgrade failed (1)</code></p>
