getState<T> method

int getState<T>({ required MultiStateSheetExtent<T> extent, required double offset, })

Gets the state associated with the specified offset.

• extent: The current extent of the sheet.
• offset: The offset value to evaluate.
• Returns: The state index corresponding to the offset.

Implementation

int getState<T>(
        {required MultiStateSheetExtent<T> extent, required double offset}) =>
    cachedState.putIfAbsent(extent.offset, offset, () {
      final (firstOffset, lastOffset) = getClosestOffsets(offset, extent);

      if ((offset - lastOffset).abs() >= (offset - firstOffset).abs()) {
        return getStateFromOffset(firstOffset, extent);
      }

      return getStateFromOffset(lastOffset, extent);
    });
