FakeKeyboardPainter class

The slab: a suggestion strip, three letter rows, a bottom row with a space bar, and whatever band the platform leaves below it.

Proportional to the box it is given rather than to a key size, because the box is a measurement — an iPhone SE's 260 points and an iPad Pro's 501 hold the same rows at different sizes, which is what real keyboards do.

Constructors

FakeKeyboardPainter({required DevicePlatform? platform, required bool dark, KeyboardVariant variant = KeyboardVariant.letters})

Properties

dark → bool
final
hashCode → int
The hash code for this object.
no setterinherited
labels → List<String>
Every label this keyboard draws, in drawing order.
no setter
platform → DevicePlatform?
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semanticsBuilder → SemanticsBuilderCallback?
Returns a function that builds semantic information for the picture drawn by this painter.
no setterinherited
variant → KeyboardVariant
Which keyboard to draw. The picture changes on every device, even where the height does not: an iPad gives a number field the same 405.5 points as a text field and a completely different set of keys, and a screenshot that showed letters there would be describing a field the app never asked for.

Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
hitTest(Offset position) → bool?
Called whenever a hit test is being performed on an object that is using this custom paint delegate.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Size size) → void
Called whenever the object needs to paint. The given Canvas has its coordinate space configured such that the origin is at the top left of the box. The area of the box is the size of the size argument.
override
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies when it is time to repaint.
inherited
shouldRebuildSemantics(covariant CustomPainter oldDelegate) → bool
Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
inherited
shouldRepaint(covariant FakeKeyboardPainter old) → bool
Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
override
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
