TextField typing is backwards on linux mobile #97032
Description
Hello,
I have this annoying problem that i want to try and debug, when running a flutter application on phosh(a linux mobile interface) it starts off fine apart from the keyboard not automatically appearing but after you switch apps or open the notification shade and probably anything else that loses focus of the app input breaks completely, keyboard starts auto appearing when touching input boxes but every key press now resets for cursor back to the start of the text box so if you just keeping typing without manually moving the cursor to where it should be you appear to be typing backwards. So i have gotten as far as pulling the engine and building it once but not too sure what to look at next so was wanting some tips
Steps to Reproduce
- Execute
flutter runon the code sample - type something using onscreen keyboard
- switch apps
- and now you typing backwards
probably a bit difficult for people to test because it kinda requires a linux device with a touch screen to test properly but seems like you can still reproduce using mouse on the on screen keyboard you can download a mobian image from here to quickly have a phosh install for testing
Expected results:
Actual results:
