Do i need to use the FlutterTagger always as a bottomNavigationBar widget?

[SmearyQuill]

i'm trying to add the tagging feature to my app using the plugin flutter_chat_ui from here: https://pub.dev/packages/flutter_chat_ui
i took some sample code from the examples of that plugin and i placed the FlutterTagger as a wrapper for the TextField that was already available but the tag list is not visible, i used Flutter dev tools and discovered that the overlay has always a width = 0, debbuging the code of fluttertagger i find out that his code is failing:

try { final renderBox = _textFieldKey.currentContext!.findRenderObject() as RenderBox; width = renderBox.size.width; offset = renderBox.localToGlobal(Offset.zero); } catch (_) {}
so the width is always 0 but im not sure why the _textFieldKey.currentContext could be null and fail.

thanks in advance!

It’ll help if you can include a minimal reproducible code sample.

However it is likely that you’re not passing the key from the FlutterTagger builder to the TextField widget.

Hi thanks for the quick response, you can find the minimal code sample here:

@SmearyQuill, you're not passing the key from FlutterTagger's builder to your TextField.

Do this:

// truncated code above here...
builder: (context, containerKey) => TextField(
  key: containerKey, // pass the key
  controller: _textController,
  decoration: InputDecoration(
      hintText: widget.hintText,
// .. the rest of your code
