I have a flutter app that is running across android,ios and web. I have different pages that contain multiple textfields for the user to fill his info and signup/login. The textfields display no problems in the apk or the .app in ios. The main problem is in web when opened from an iphone (ios) . The behavior is not consistent on all iphones but the main problem is that either the texfields flicker/disappear or the transition from a textfield to another takes about 12 seconds. A video is attached below to show the behavior on iphone 6 safari browser (the same happens with chrome). Other iphones show a delay between the transition from a textfield to another(tested on iphone 11) Flutter doctor : [√] Flutter (Channel stable, 2.2.3, on Microsoft Windows [Version 10.0.19042.1110], locale en-US) • Flutter version 2.2.3 at D:\flutter-src\flutter • Framework revision f4abaa0735 (5 weeks ago), 2021-07-01 12:46:11 -0700 • Engine revision 241c87ad80 • Dart version 2.13.4
