Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
shouldUpdateMatrix(
ViewConfiguration oldConfiguration) → bool -
Returns whether toMatrix would return a different value for this
configuration than it would for the given
oldConfiguration. -
toMatrix(
) → Matrix4 - Creates a transformation matrix that applies the devicePixelRatio.
-
toPhysicalSize(
Size logicalSize) → Size - Transforms the provided Size in logical pixels to physical pixels.
-
toString(
) → String -
A string representation of this object.
