Allow omitting parentheses for Expression.asA(Expression other)

[Robbendebiene]

Expression.asA(Expression other) always wraps the code into parentheses. While this is a good default it is not always necessary. The problem for me is that the generated code triggers the linter rule unnecessary_parenthesis in our CI. Unfortunately dart_style auto fixes does not support the removal of unnecessary parenthesis.

My suggestion would be to have an optional parameter.
the following:

code_builder/lib/src/specs/expression.dart

Lines 68 to 73 in 006790d

	Expression asA(Expression other) =>
	ParenthesizedExpression._(BinaryExpression._(
	expression,
	other,
	'as',
	));

becomes

  Expression asA(Expression other, { bool parenthesized = true }) {
     final exp = BinaryExpression._( expression, other,  'as'));
     return parenthesized
        ? ParenthesizedExpression._(exp)
        : exp
  }

We typically recommend avoiding that type of style lint for generated code. As mentioned in #213 readability is not a goal for the generated output from this package. This is a relatively easy change though, and most of the complexity stays in the calling code deciding what value to pass.

@srawlins do you have any opinions on adding this option?

Yeah I think that supporting a parenthesized parameter everywhere (it's not just asA right?) would add a fair amount of complexity.

I recommend using // ignore_for_file: type=lint for generated files. See https://dart.dev/tools/analysis#suppressing-rules-for-a-file.
