Given that this function is out-of-line, don't we need to export the class to
make it link in the component build?

class PLATFORM_EXPORT PlatformKeyboardEvent : public PlatformEvent {

+
+    // Text as as generated by processing a virtual key code with a keyboard layout
+    // (in most cases, just a character code, but the layout can emit several
+    // characters in a single keypress event on some platforms).
+    // This may bear no resemblance to the ultimately inserted text if an input method
+    // processes the input.
+    // Will be null for KeyUp and RawKeyDown events.
+    String text() const { return m_text; }
+
+    // Text that would have been generated by the keyboard if no modifiers were pressed
+    // (except for Shift); useful for shortcut (accelerator) key handling.
+    // Otherwise, same as text().
+    String unmodifiedText() const { return m_unmodifiedText; }
+
+    String keyIdentifier() const { return m_keyIdentifier; }
+
+    // Most compatible Windows virtual key code associated with the event.

We usually have a blank line above this line.
