Undefined name 'E'

Line gives an error:

Undefined name 'E'

dart-bitcoin/lib/src/core/bloom_filter.dart

Line 79 in 5404961

return pow(1 - pow(E, -1.0 * (hashFuncs * elements) / (data.length * 8)), hashFuncs);

Using Dart2. Should it just be lowercase?

It seems that the variable E changed in Dart v2.

So, this is the one we need: https://api.dartlang.org/stable/2.0.0/dart-math/e-constant.html
