writeValues static method

void writeValues(Position position, StringSink buffer, { String delimiter = ',', int? decimals, bool compactNums = true, bool swapXY = false, })

Writes coordinate values of position to buffer separated by delimiter.

Use decimals to set a number of decimals (not applied if no decimals).

If compactNums is true, any ".0" postfixes of numbers without fraction digits are stripped.

Set swapXY to true to print y (or latitude) before x (or longitude).

A sample with default parameters (for a 3D point): 10.1,20.3,30.3

To get WKT compatible text, set delimiter to : 10.1 20.2 30.3
