How to declare multiple required variables on one line in Dart, Flutter?
257
It is currently not possible to summarize required parmeters. The Language Specification [1] requires that all are listed and fully written out.
Besides the Language Specification you can also have a look at the BNF of the language (e.g. this issue [2] provides some links to BNFs).

For shorter code, we can declare variables in one line. For example:
late String day1, day2, day3, day4, day5, day6, day7;
But how to declare required variables in the same way?
required this.day1, required this.day2, required this.day3, required this.day4, required this.day5, required this.day6, required this.day7,

OMi Shah over 2 yearsbut why do you need to specify
required
at a point where you haven't even declared your variables? What's the point?
