getDistanceToActualBaseline method

  1. @protected
  2. @mustCallSuper
double? getDistanceToActualBaseline(
  1. TextBaseline baseline
)

Calls computeDistanceToActualBaseline and caches the result.

This function must only be called from getDistanceToBaseline and computeDistanceToActualBaseline. Do not call this function directly from outside those two methods.

Implementation

@protected
@mustCallSuper
double? getDistanceToActualBaseline(TextBaseline baseline) {
  assert(
    _debugDoingBaseline,
    'Please see the documentation for computeDistanceToActualBaseline for the required calling conventions of this method.',
  );
  return _computeIntrinsics(
    _CachedLayoutCalculation.baseline,
    (constraints, baseline),
    ((BoxConstraints, TextBaseline) pair) =>
        BaselineOffset(computeDistanceToActualBaseline(pair.$2)),
  ).offset;
}
