toString method Null safety

String toString()

Provide a representation of this double value.

The representation is a number literal such that the closest double value to the representation's mathematical value is this double.

Returns "NaN" for the Not-a-Number value. Returns "Infinity" and "-Infinity" for positive and negative Infinity. Returns "-0.0" for negative zero.

For all doubles, d, converting to a string and parsing the string back gives the same value again: d == double.parse(d.toString()) (except when d is NaN).
