RawKeyEventDataLinux class

Platform-specific key event data for Linux.

This class is deprecated and will be removed. Platform specific key event data will no longer be available. See KeyEvent for what is available.

Different window toolkit implementations can map to different key codes. This class will use the correct mapping depending on the keyHelper provided.

Properties

hashCode → int
The hash code for this object.
no setteroverride
isAltPressed → bool
Returns true if a ALT modifier key was pressed at the time of this event, regardless of which side of the keyboard it is on.
no setterinherited
isControlPressed → bool
Returns true if a CTRL modifier key was pressed at the time of this event, regardless of which side of the keyboard it is on.
no setterinherited
isDown → bool
Whether or not this key event is a key down (true) or key up (false).
final
isMetaPressed → bool
Returns true if a META modifier key was pressed at the time of this event, regardless of which side of the keyboard it is on.
no setterinherited
isShiftPressed → bool
Returns true if a SHIFT modifier key was pressed at the time of this event, regardless of which side of the keyboard it is on.
no setterinherited
keyCode → int
The hardware key code corresponding to this key event.
final
keyHelper → KeyHelper
A helper class that abstracts the fetching of the toolkit-specific mappings.
final
keyLabel → String
Returns the Unicode string representing the label on this key.
no setteroverride
logicalKey → LogicalKeyboardKey
Returns an object representing the logical key that was pressed.
no setteroverride
modifiers → int
A mask of the current modifiers using the values in Modifier Flags. This value may be different depending on the window toolkit used. See KeyHelper.
final
modifiersPressed → Map<ModifierKey, KeyboardSide>
Returns a map of modifier keys that were pressed at the time of this event, and the keyboard side or sides that the key was on.
no setterinherited
physicalKey → PhysicalKeyboardKey
Returns an object representing the physical location of this key on a QWERTY keyboard.
no setteroverride
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scanCode → int
The hardware scan code id corresponding to this key event.
final
specifiedLogicalKey → int?
A logical key specified by the embedding that should be used instead of deriving from raw data.
final
unicodeScalarValues → int
An int with up to two Unicode scalar values generated by a single keystroke. An assertion will fire if more than two values are encoded in a single keystroke.
final

Methods

debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
override
getModifierSide(ModifierKey key) → KeyboardSide
Returns a KeyboardSide enum value that describes which side or sides of the given keyboard modifier key were pressed at the time of this event.
override
isModifierPressed(ModifierKey key, {KeyboardSide side = KeyboardSide.any}) → bool
Returns true if the given ModifierKey was pressed at the time of this event.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
shouldDispatchEvent() → bool
Whether a key down event, and likewise its accompanying key up event, should be dispatched.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
inherited

Operators

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