Empty space on TextField bug when using Chinese Keyboard (iOS) #79025
Description
I encountered this bug when developing the login screen for an app. Where myemail@email.com will changed to myemail@email.co m when using a Chinese keyboard. This issue is not found on vanilla iOS application. This can be solved temporarily via setting the FilteringTextInputFormatter.deny(RegExp('[\\s]')).
Steps to Reproduce
- Run
flutter create bug. - Update the
main.dartto include the follow:Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ TextField( keyboardType: TextInputType.text, ), TextField( keyboardType: TextInputType.emailAddress, ), ], ) - Change to Chinese Keyboard via iOS settings
- Type text with Chinese shorthand. Example, p g => 苹果. Before the Chinese character is selected. Click on the other textfield
Expected results:
Created with a sample Swift UI project with 2 TextFields
nativeswift.MP4
Actual results:
flutter.MP4
