<h2 dir="auto">Steps to Reproduce</h2>
<ol dir="auto">
<li>Create an app with a material <code class="notranslate">Input</code> widget.</li>
<li>Create a <code class="notranslate">test_driver</code> test that tries to <code class="notranslate">driver.setInputText...</code></li>
<li>Attempt to run test on Android Device</li>
<li>Encounter error <code class="notranslate">DriverError: Failed to fulfill SetInputText due to remote error</code></li>
</ol>
