FTypography class final

The typographical tokens grouped by their semantic roles.

CJK Text Alignment

When using CJK (Chinese, Japanese, Korean) scripts, text may appear vertically misaligned. This is a known Flutter issue.

As a temporary workaround, wrap the affected widget in a DefaultTextStyle with the appropriate TextHeightBehavior:

DefaultTextStyle.merge(
  textHeightBehavior: const TextHeightBehavior(
    applyHeightToFirstAscent: false,
    applyHeightToLastDescent: false,
  ),
  child: FButton(
    onPressed: () {},
    child: const Text('按钮'),
  ),
)
