title: Change default gradle settings (distributionUrl) when creating new Flutter project
body: <p>What I would like is to change the &quot;new flutter project settings&quot; so that the file in the file   <code>android/gradle/wrapper/gradle-wrapper.properties</code>, the value for <code>distributionUrl</code> is <code>distributionUrl=https\://services.gradle.org/distributions/gradle-6.8-milestone-2-all.zip</code> rather than <code>distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip</code>.</p>
  <p>Creating a project in VSCode through <code>ctrl+shift+p</code>, <code>Flutter: New Project</code>.</p>
  <p>Any leads on how to do this would be greatly appreciated!</p>
