DartPad Not Supporting ON Clause
I'm learning Dart Language by working with dart code in DartPad.
While using on clause in Exception it throws uncaught exception.

That was added to Dart only very recently. It's likely DartPad needs an update. Please create an issue in github.com/dart-lang/dart-pad/issues

This use ofonis not new, it's been there for years. It's only themixindeclaration which is new.

You are right of course. Didn't even look at the code because the screenshot was shown too small on my phone and I assumed it's about mixins.

The issue here is that dart2js, which DartPad is based on, does not throw an IntegerDivisionByZeroException (which should really be named DivisionByZeroError, but alas, isn't) when you do integer division by zero.
It throws, but it's using UnsupportedError instead, which is otherwise a good choice for such an error.
Dart2js is not wrong. Neither the language specification, nor the library documentation for num.~/ says that it should throw that particular error type. Still, it's inconsistent with the other compilers, so we may want to make it consisent.
