Feature Request: Bracketless lambda argument

[FiercestT]

Currently when writing an anonymous function with a lambda, I've noticed that even with only one argument, we are forced to enclose the argument in brackets.

E.g.

someFuture.then((oneArg) => doSomething(oneArg));
someFuture.then((l) => doSomething(l));

It would be simple and nice QOL if we could do it like:

someFuture.then(oneArg => doSomething(oneArg));
someFuture.then(l => doSomething(l));

Java supports this and makes it a bit less of a brackety mess.
I'm not sure if there's some other technical feature blocking this feature being added.

Thanks!

This sounds more like a change to the language specification which has its own repository: https://github.com/dart-lang/language/issues
