Is there a constant for max/min int/double value in dart?

I found this from dart_numerics package.

For double there are

double.maxFinite (1.7976931348623157e+308)
double.minPositive (5e-324)

In Dart 1 there was no such number for int. The size of integers was limited only by available memory

In Dart 2 int is limited to 64 bit, but it doesn't look like there are constants yet.

For dart2js different rules apply

When compiling to JavaScript, integers are therefore restricted to 53 significant bits because all JavaScript numbers are double-precision floating point values.
