Interesting — thanks for the link! I really hope they aren’t too late to get non-nullable by default into the language as well... seems like it would influence a lot of the language design ...
I personally found typescript almost impossible to use until turning on the non-nullable by default option and no implicit any (and really started liking it after). I see dart had “no implicit dynamic” — is that widely used in dart? I would turn that on with a quickness ...
Reliable constraints were really important for me to figure out how to use the the optional typing model of typescript to my benefit. Maybe Dart’s programming model is simpler since it doesn’t maintain JavaScript compatibility... but my suspicion is that features like implicit-dynamic and nullable types will just make it harder to learn how to interpret compiler errors and harder to learn how to write good code in the language...
