title: How to fix multiple SDK path warning in flutter project
body: <p>I change sdk file then when i run the project it shows this error</p>
  <pre><code>Warning! The 'flutter' tool you are currently running is from a different Flutter repository than the one last used by this package. The repository from which the 'flutter' tool is currently executing will be used instead.
    running Flutter tool: C:\Users\LENOVO\Desktop\flutter
    previous reference  : C:\src\flutter
  This can happen when you have multiple copies of flutter installed. Please check your system path to verify that you are running the expected version (run 'flutter --version' to see which flutter is on your path).
