LayoutConstraints class final

The range of sizes a layout item may choose from when it lays itself out.

Mirrors Flutter's BoxConstraints, but implemented using Vector2.

Constructors

LayoutConstraints({required Vector2 min, required Vector2 max}): const
LayoutConstraints.loose(Vector2 size): Zero to size in both axes. Aliases size rather than copying, so it must already be immutable - this is checked with an assertion. Copy a mutable size with Vector2.copy first if needed.
const
LayoutConstraints.tight(Vector2 size): Exactly size in both axes. Aliases size rather than copying, so it must already be immutable - this is checked with an assertion. Copy a mutable size with Vector2.copy first if needed.
const
LayoutConstraints.unbounded(): No minimum; unbounded maximum, in both axes.
const

hasBoundedHeight → bool: Whether max's y component is finite.
no setter
hasBoundedWidth → bool: Whether max's x component is finite.
no setter
hashCode → int: The hash code for this object.
no setteroverride
isTight → bool: Whether min and max are equal in both axes.
no setter
max → Vector2: The largest size satisfying these constraints. Either component may be double.infinity, meaning unbounded in that axis.
final
min → Vector2: The smallest size satisfying these constraints.
final
runtimeType → Type: A representation of the runtime type of the object.

constrain(double x, double y) → Vector2: The size closest to (x, y) that satisfies these constraints.
deflate(EdgeInsets padding) → LayoutConstraints: These constraints with padding subtracted from min and max, clamping both so neither drops below zero and max never ends up below the deflated min.
descale(Vector2 scale) → LayoutConstraints: These constraints, carried from a parent's space into the space of an item scaled by scale.
enforce(LayoutConstraints other) → LayoutConstraints: These constraints, pulled inside other.
loosen() → LayoutConstraints: These constraints with min cleared to zero, keeping max.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
