<p dir="auto">If there are two textFields in the screen.<br>
when I input text at the first textField in Chinese Pin Yin<br>
then I tap the second textField and the second textField become first responser.<br>
The app crash.</p>
<p dir="auto"><a target="_blank" rel="noopener noreferrer nofollow" href="https://user-images.githubusercontent.com/20470157/48749452-ff399680-ecb5-11e8-8b1d-2fd22df0e6b8.png"><img src="https://user-images.githubusercontent.com/20470157/48749452-ff399680-ecb5-11e8-8b1d-2fd22df0e6b8.png" alt="textfieldbug" style="max-width: 100%;"></a></p>
<p dir="auto">My app crash when clear() on TextEditingController is run while a user is composing Japanese in TextField.<br>
It might be caused on not only Japanese but also languages that have composing state.<br>
Maybe it's only for iOS devices. It isn't caused in my Android device.</p>
<h2 dir="auto">Steps to Reproduce</h2>
<ol dir="auto">
<li>Compose Japanese text in TextField using TextEditingController.</li>
<li>Run clear() while composing text.</li>
<li>Then the app will crash.</li>
</ol>
<p dir="auto">My minimum example is here.<br>
If you tap clear button while composing text, the app will crash.</p>
