Yup. It got it's second life because Flutter adopted it as it's language.

It was pretty dead for a few years (despite what the googlers will tell you...)

It absolutely is and its a pleasant language to work with. Although it is in a kinda-symbiotic relationship with Flutter, I've found myself using it for small scripts and cli tools instead of Python because of its strong+static typing with null safety.

Relevant to the topic, Dart (and Flutter) supports targeting wasm.

Not only a thing but is growing at a crazy rate. Easily my favourite language out there for the last few years.
