title: How to add debug symbols to build.gradle
body: <p>I have created android build of my Flutter application.</p>
  <p>Then I created an internal testing release. It is showing a warning</p>
  <blockquote>
  <p>This App Bundle contains native code, and you've not uploaded debug
  symbols. We recommend you upload a symbol file to make your crashes
  and ANRs easier to analyze and debug.</p>
  </blockquote>
  <p>Basically what I had to do is add following to build.gradle file according to the link they show.</p>
  <pre><code>android.buildTypes.release.ndk.debugSymbolLevel = { SYMBOL_TABLE | FULL }
  </code></pre>
  <p>I assume it is android/app/build.gradle they are talking about.</p>
  <p>Not sure exactly where in that file I have to add this line.</p>
  <p>Can someone point out where to add this line?</p>
