Issue
I am new in Flutter. I face a problem about Flutter: Unhandled Exception: FormatException: Unexpected character (at character 1).
This is my Debug Console:
E/flutter ( 8328): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: FormatException: Unexpected character (at character 1)
E/flutter ( 8328): <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">

How do I fix it?
Solution
Well, you fix it by not parsing an HTML text as JSON in your build method of the _UserCreateEnquiryScreenState class.
Since you posted no code and no other explanation, that is all the help we can give you.
