verticalLineLeft property

bool get verticalLineLeft

Determines if there's a vertical line on the left side of the matrix.

This getter lazily evaluates and caches the result of checking for a vertical line on the left side of the matrix. It uses the _hasVerticalLineLeft method to perform the actual check.

Returns: A boolean value:

• true if a vertical line is present on the left side
• false otherwise

The result is cached after the first call for efficiency in subsequent accesses.

Implementation

bool get verticalLineLeft {
  _verticalLineLeft ??= _hasVerticalLineLeft(this);
  return _verticalLineLeft!;
}
