- レーンサイズがファイルのセーブ・ロード時にも反映されるようにした。
- 縦レーンの横幅調整機能を実装した。
- 画面をパンしすぎたときに横レーンの区切り線がヘッダーと離れないようにしたり、縦レーンのヘッダーを小さくしたときにエラーが出ないようにするなど細かい点を改善。
2023/05/20
- ログを重要度に応じて出力できるようにした。
- リレーションの改善
- 横レーン内の縦スクロール時、リレーションがずれていたのを修正。また線の両端が画面内に収まらない場合は色が薄くなるような対応も入れた。(図)
2023/05/21
- 細かな調整を実施
- キャンバスのスクロールバーの挙動を修正して縦スクロールバーが出ていないときは横幅いっぱいまで描画
- ヘッダー幅を変更したときの挙動修正、縦レーンを追加したときの不具合修正やデバッグログの内容改善などを行った

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number is used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
# In Windows, build-name is used as the major, minor, and patch parts
# of the product and file versions while build-number is used as the build suffix.

# The "flutter_lints" package below contains a set of recommended lints to

# included with your application, so that you can use the icons in
# the material Icons class.

# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
#
# For details regarding fonts from package dependencies,
