kivyで作成したプロジェクトをpyinstallerでexeファイル化したい。

Question

実現したいこと

kivyで作成したプロジェクトをpyinstallerでexeファイル化したい。

前提

pythonのkivyを使って作ったプロジェクトをexeファイルとしてビルドしようとしています。
poetryでパッケージの依存関係を管理していたのですが、pyinstallerが参照する依存関係はまた別物ということで
一度目のビルドで足りていなかったローカルの依存関係をspecファイルに別途記載してからビルドするなどして、
1度目のビルドで発生した依存関係のエラーまでは解決できました。
しかし、新たに依存関係によるエラーが発生しました。これは、一度目のビルドで足りていなかった依存関係の子に当たる部分なので本来は発生しないものと考えています。
KV言語の特有のエラーかと思われるのですが、知見が足りないためお力を貸していただきたいです。

該当のソースコード

KV言語内のimportでエラーが発生しているようです。

試したこと

下記、wat.specに必要そうな記載を一通り行ってみました。
'# -- mode: python ; coding: utf-8 --
block_cipher = None
a = Analysis(

pathex=['D:/GitHub/wat', 'D:/GitHub/wat/src', 'D:/GitHub/wat/src/ui/components'],

pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(

補足情報（FW/ツールのバージョンなど）

実際のフォルダ構成は下記の様になっています。
main.pyを起動して、talkroom.pyを呼び出し、message_input_field.pyをインポートしようとしています。

D:/GitHub/wat
├── pyproject.toml
├── src
｜ └── ui
｜ ├── components
｜ ｜ ├── init.py
｜ ｜ └── message_input_field.py
｜ ├── init.py
｜ ├── namelist.py
｜ └── talkroom.py
├────── main.py
└────── settings.py

よろしくお願いいたします。

Answer 1

I really like reading what you've written. Play football legends for fun every day

Answer 2

自己解決しました。
python上にKV言語でインポートしようとしているクラスのimport文を追記して少々強引ですが、モジュールを認識させることができました。

from src.ui.components.message_input_field import MessageTextField #追記

KV = '''
#:import MessageTextField src.ui.components.message_input_field.MessageTextField 
<TalkRoomScreen>:
    #画面全体のレイアウト

もっといいやり方がありそうですが、今回はこちらのやり方で行こうと思います。
読み返してみるとなかなかの駄文による質問でお目汚し失礼いたしました…。
