This issue was originally filed by @ahmetaa

Float32List, Float64List and Float32x4List constructors with List<num> or List<double> input. It seems fairly common to initialize those objects with List<> input. Currently I need to use methods like

Float32x4List toFloat32x4List(List<double> list)
or
Float32List toFloat32List(List<double> input)

Reverse methods are also needed. Such as

List<double> toDoubleList(Float32x4List lst)

If there is a more generic solution to this, (some kind of List->ByteBuffer transformation) of course that would be more preferable.

These constructors exist, it's, e.g. new Float64List.from(listOfDoubles).
