Properties
- backgroundColor → Color
-
Grid background color.
final
- gridColor → Color
-
Grid lines color.
final
- gridSquare → double
-
size of the grid square with scale applied
no setter
- gridThickness → double
-
Thickness of lines.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- offset ↔ Offset
-
getter/setter pair
- rawGridSquareSize → double
-
Unscaled size of the grid square
i.e. the size of the square when scale is 1
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- scale ↔ double
-
Scale of the grid.
getter/setter pair
- secondarySquareStep → int
-
How many vertical or horizontal lines to draw the marked lines.
final
Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
addOnScaleUpdateListener(
void listener(double scale)) → void - Add listener for scaling
-
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
removeOnScaleUpdateListener(
void listener(double scale)) → void - Remove listener for scaling
-
setScale(
double factor, Offset focalPoint) → void -
toMap(
) → Map< String, dynamic> -
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
