i mean there 

<textField id="user.First_Name" label="Enter your first name" value="super_user">

this behavior crash expressions parser

OndrejKunc commented 3 years ago

I added _ as an allowed character in the identifier. The . cannot be used, because it can be used in the expressions to reference properties so there will be a conflict. I added this log to the parser, whenever there is a prohibited character:

  developer.log(
    'Warning: Invalid identifier \'$id\' for element type $TFormElement in FormElementParser.\n'
    'Only alphanumerics characters and underscores are allowed and identifiers cannot start with a number.',
    level: 900, // 900 relates to Warning according to the package:logging
  );

It is already merged and published together with the null safety version, so I am closing it now.
