title: Flutter android app crashes upon startup if I include a certain package
body: <p>A problem has suddenly recently arisen such that simply by including the  dependency in 'location' in pubspec.yaml like e.g. </p>
  
  <pre><code>dependencies:
    flutter:
      sdk: flutter
  
    location: ^1.2.0  &lt;------------------------ culprit
    firebase_auth: ^0.5.10  
    cloud_firestore: ^0.7.2   
  
  the app crashes immediately upon startup.
  </code></pre>
  
  <p>The 'location' package itself works when alone in an example app.
  I am not currently importing i.e. using any of the functionality contained within the location package, yet when I remove the entry, all is well.</p>
  
  <p>No clues from watching flutter log unfortunately...</p>
