Question

Answer 1

Dart 2

For dart2js generated JavaScript Pixel Elephants answer is still true.

within the range -2⁵³ to 2⁵³

Other execution platforms have fixed-size integers with 64 bits.

The type BigInt was added to typed_data

Since Dart 2.0 will switch to fixed-size integers, we also added a BigInt class to the typed_data library. Developers targeting dart2js can use this class as well. The BigInt class is not implementing num, and is completely independent of the num hierarchy.
