FTypography class final

The typographical tokens.

A FTypography contains scalar values for scaling a TextStyle's corresponding properties. It also contains labelled font sizes, such as FTypography.xs, which are based on Tailwind CSS.

The scaling is applied automatically in all Forui widgets while the labelled font sizes are used as the defaults for the corresponding properties of widget styles configured via inherit(...) constructors.

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'),
  ),
)
