discontinuedPackage jet_cad_floor_plan has been discontinued and replaced by jet_cad_2d_plan.

GhostMatrix class final

The ghost's reused matrix (spec 09b D6, 09c D5): the placement transform P is handed in by the tool, which computes it on pointer, key, camera and re-arm events (spec 09c D12); its linear part is written only when one of its six doubles differs from the last (update); a paint (forOrigin) writes only the translation less the rebase origin.

Constructors

GhostMatrix()

Properties

computations → int

How many times a new P was taken: a test's count (spec D6).

no setter

hashCode → int

The hash code for this object.

no setter, inherited

placement → Transform2?

The current placement transform, or null before the first update.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

storage → Float64List

The column-major storage handed to canvas.transform, reused for the holder's life.

final

Methods

forOrigin(Vector2 origin) → Float64List

storage with its translation set for origin (world − origin, the frame paintWorldOverlay paints in). Call update first.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

update({required Transform2 placement}) → void

Sets the placement; takes placement and rewrites the linear part only when one of its six doubles differs from the last call's (stored values, compared exactly with ==, so -0.0 equals 0.0). An equal placement keeps the earlier object.

Operators

operator ==(Object other) → bool

The equality operator.
