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) {
  // This method handles text editing state updates from the platform text
  // input plugin. The [EditableText] may not have the focus or an open input
  // connection, as autofill can update a disconnected [EditableText].

  // Since we still have to support keyboard select, this is the best place
  // to disable text updating.
  if (!_shouldCreateInputConnection) {
    return;
  }

  // // In the read-only case, we only care about selection changes, and reject
  // // everything else.

  value = _value.copyWith(selection: value.selection);

  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.
    setState(() {
      _value = _value.copyWith(selection: value.selection);
      _handleSelectionChanged(
          value.selection, SelectionChangedCause.keyboard);
    });
  } else {
    //hideToolbar();
    textEditingValue = value;
  }
}
