title: How to fix flutter or dart mismatch version?
body: <p>When I ran my flutter project, it gave me this error</p>
  <pre><code>The current Dart SDK version is 2.17.0-105.0.dev.
  
  Because lints 2.0.0 requires SDK version &gt;=2.17.0-206.0.dev &lt;3.0.0 and no versions of lints match &gt;2.0.0 &lt;3.0.0, lints ^2.0.0 is forbidden.
  
  So, because firebase_flutter depends on flutter_lints ^2.0.0 which depends on lints ^2.0.0, version solving failed.
  
  pub get failed (1; So, because firebase_flutter depends on flutter_lints ^2.0.0 which depends on lints ^2.0.0, version solving failed.)
  </code></pre>
