• BoxConstraints

Methods

axisConstraints(Axis axis) → BoxConstraints

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Returns box constraints with the same axis constraints but with an unconstrained cross axis.

constrainAxis(Axis axis, [double extent = double.infinity]) → double

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Returns the value that both satisfies the constraints and is as close as possible to the given extent on axis.

constrainAxisDimensions(Axis axis, double cross, double main) → Size

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Returns the size that both satisfies the constraints and is as close as possible to the given cross and main size.

constrainCrossAxis(Axis axis, [double extent = double.infinity]) → double

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Returns the value that both satisfies the constraints and is as close as possible to the given extent crossing axis.

copyWithAxis(Axis axis, {double? minCross, double? maxCross, double? minMain, double? maxMain}) → BoxConstraints

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Creates a copy of this box constraints but with the given fields replaced with the new values.

crossAxisConstraints(Axis axis) → BoxConstraints

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Returns box constraints with the same cross axis constraints but with an unconstrained main axis.

hasBoundedAxis(Axis axis) → bool

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Whether there is an upper bound on the maximum extent of the given axis.

hasBoundedCrossAxis(Axis axis) → bool

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Whether there is an upper bound on the maximum extent crossing the given axis.

hasInfiniteAxis(Axis axis) → bool

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Whether the constraint for the given axis is infinite.

hasInfiniteCrossAxis(Axis axis) → bool

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Whether the constraint crossing the given axis is infinite.

hasTightAxis(Axis axis) → bool

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Whether there is exactly one value that satisfies the constraints on the given axis.

hasTightCrossAxis(Axis axis) → bool

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Whether there is exactly one value that satisfies the constraints crossing the given axis.

maxAxis(Axis axis) → double

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

The maximum value that satisfies the constraints on the given axis.

maxCrossAxis(Axis axis) → double

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

The maximum value that satisfies the constraints crossing the given axis.

minAxis(Axis axis) → double

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

The minimum value that satisfies the constraints on the given axis.

minCrossAxis(Axis axis) → double

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

The minimum value that satisfies the constraints crossing the given axis.

tightenAxis(Axis axis, {double? cross, double? main}) → BoxConstraints

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Returns new box constraints with a tight main and/or cross axes.

Static Methods

create(Axis axis, {double minCross = 0.0, double maxCross = double.infinity, double minMain = 0.0, double maxMain = double.infinity}) → BoxConstraints

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Creates box constraints with the given constraints.

expand(Axis axis, {double? cross, double? main}) → BoxConstraints

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Creates box constraints that expand to fill another box constraints.

tightFor(Axis axis, {double? cross, double? main}) → BoxConstraints

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Creates box constraints that require the given cross or main size.

tightForFinite(Axis axis, {double cross = double.infinity, double main = double.infinity}) → BoxConstraints

Available on BoxConstraints, provided by the BoxConstraintsAxisUtil extension

Creates box constraints that require the given cross or main size, except if they are infinite.
