Setting TextEditingController text to empty raises exception on Android #11041
Description
Steps to Reproduce
Set the text property of a TextEditingController to the empty string throws a confusing error. I'm forced to use the clear method. This works fine but is a bit annoying since I have to check if the string is empty and, if so, call clear() instead.
Perhaps this is not a big just a documentation issue -- programmers should account for the empty string and call the clear() method instead -- but I can't find anything that indicates this should be the case. Either way, the error thrown was quite confusing.
