I have a RichText containing three children. the first and last inlineSpans are TextSpan, The Second one is WidgetSpan.
they are correctly laid out in the android application:

but when I build web application in flutter stable channel, RichText goes like this:

I also tried building web application in flutter beta and dev channels and they both were like this:

in flutter beta and dev channels there was also another issue that the border color of selected TextFields becomes blue which must be application primaryColor:

• android and web text field in stable channel(the correct one):
  

• web text field in beta and dev channels (wronge one):
  

I didn't have these problems in the old version of flutter beta channel (before flutter web was merged to stable channel)
I think this issues must be solved in the flutter framework itself!
