<itemvalue="A generic position in a two-dimensional space, expressed as a pair of coordinates (that can be either integer or double)."/>
<itemvalue="[RawKeyboard] is the legacy API, and will be deprecated and removed in the future. It is recommended to always use [HardwareKeyboard] and [KeyEvent] APIs (such as [FocusNode.onKeyEvent]) to handle key events."/>
<itemvalue="Flutter will try to synchronize with the ground truth of keyboard states using synthesized events ([KeyEvent.synthesized]), subject to the availability of the platform. The desynchronization can be caused by non-empty initial state or a change in the focused window or application. For example, if CapsLock is enabled when the application starts, then immediately before the first key event, a synthesized [KeyDownEvent] and [KeyUpEvent] of CapsLock will be dispatched. The resulting event stream does not map one-to-one to the native key event stream. Some native events might be skipped, while some events might be synthesized and do not correspond to native events. Synthesized events will be indicated by [KeyEvent.synthesized]."/>
<itemvalue="When the Flutter application starts, all keys are released, and all lock modes are disabled. Upon key events, [HardwareKeyboard] will update its states, then dispatch callbacks: [KeyDownEvent]s and [KeyUpEvent]s set or reset the pressing state, while [KeyDownEvent]s also toggle lock modes."/>
