title: Error after running "flutter upgrade"
body: <p>I am getting the following error after running <code>flutter upgrade</code>:</p>
  
  <blockquote>
    <p>Because every version of flutter_test from sdk depends on path 1.5.1 and flutter_advanced_networkimage >=0.2.9+1 depends on path ^1.6.0, flutter_test from sdk is incompatible with flutter_advanced_networkimage >=0.2.9+1.
    So, because testapp depends on both flutter_advanced_networkimage ^0.2.10 and flutter_test any from sdk, version solving failed.
    pub upgrade failed (1)</p>

  <p>My <code>pubspec.yaml</code>:</p>
