containsOffset method
Check if {offset} is inside the rectangle
Example:
final rect = Rect.fromLTWH(0, 0, 100, 100);
final offset = Offset(50, 50);
rect.containsOffset(offset); // true
Implementation
bool containsOffset(Offset offset) {
return bottom >= offset.dy && top <= offset.dy && left <= offset.dx && right >= offset.dx;
}
