LineMetrics class Null safety

LineMetrics stores the measurements and statistics of a single line in the paragraph.

The measurements here are for the line as a whole, and represent the maximum extent of the line instead of per-run or per-glyph metrics. For more detailed metrics, see TextBox and Paragraph.getBoxesForRange.

LineMetrics should be obtained directly from the Paragraph.computeLineMetrics method.

Constructors

LineMetrics({required bool hardBreak, required double ascent, required double descent, required double unscaledAscent, required double height, required double width, required double left, required double baseline, required int lineNumber})
Creates a LineMetrics object with only the specified values.
