<h2 dir="auto">Steps to Reproduce</h2>
<p dir="auto">Seemingly out of nowhere, my app started crashing on startup. Initially I thought it might be due to recent changes, so I backed out to a prior build that I knew to be working. That also failed. So I tried with a brand new project:</p>
<ol dir="auto">
<li><code class="notranslate">flutter create repro</code></li>
<li><code class="notranslate">cd repro</code></li>
<li><code class="notranslate">flutter run</code></li>
</ol>
<p dir="auto"><em>That also fails</em>.</p>
<p dir="auto">Note that the same app built via <code class="notranslate">flutter build apk</code> does work when I deploy it to my device.</p>
<p dir="auto">I've tried:</p>
<ul dir="auto">
<li><code class="notranslate">flutter clean</code></li>
<li>restarting my machine</li>
<li>plugging/unplugging my device</li>
</ul>
<p dir="auto">None of these things worked, but switching channels to alpha did. So I assume this has to do with the fact that I upgraded flutter earlier this morning and master is currently broken? Super weird that it didn't trigger any problem for <em>hours</em> after the upgrade.</p>
