updateEditingValue method

@override void updateEditingValue(TextEditingValue value)

Requests that this client update its editing state to the given value.

The new value is treated as user input and thus may subject to input formatting.

Implementation

@override
void updateEditingValue(TextEditingValue value) {
   _lastKnownRemoteTextEditingValue = value;

  if (value == _value) {
    // This is possible, for example, when the numeric keyboard is input,
    // the engine will notify twice for the same value.
    // Track at https://github.com/flutter/flutter/issues/65811
    return;
  }

  if (value.text == _value.text && value.composing == _value.composing) {
    // `selection` is the only change.
    _handleSelectionChanged(value.selection, SelectionChangedCause.keyboard);
  } else {
    _showCaretOnScreen();
    _textSelectionDelegate.hideToolbar();
  }
  _formatAndSetValue(value, userInteraction: true, cause: SelectionChangedCause.keyboard);

  if (_hasInputConnection) {
    // To keep the cursor from blinking while typing, we want to restart the
    // cursor timer every time a new character is typed.
    _stopCursorTimer(resetCharTicks: false);
    _startCursorTimer();
  }
