RawKeyEventDataLinux class Null safety

Platform-specific key event data for Linux.

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. [...]
read-only, override
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. [...]
read-only, inherited
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. [...]
read-only, inherited
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. [...]
read-only, inherited
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. [...]
read-only, inherited
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. [...]
read-only, override
logicalKey LogicalKeyboardKey
Returns an object representing the logical key that was pressed. [...]
read-only, override
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.
read-only, inherited
physicalKey PhysicalKeyboardKey
Returns an object representing the physical location of this key on a QWERTY keyboard. [...]
read-only, override
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
scanCode int
The hardware scan code id corresponding to this key event. [...]
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

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 non-existent method or property is accessed. [...]

inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) String

inherited
toStringShort() String
A brief description of this object, usually just the runtimeType and the hashCode. [...]
