FontPicker constructor Null safety

const FontPicker(
  1. {Key? key,
  2. required void onFontFamilyChanged(
    1. String
    ),
  3. required void onFontSizeChanged(
    1. double
    ),
  4. String? initialFontFamily,
  5. double? initialFontSize}
)

Implementation

const FontPicker({
  Key? key,
  required this.onFontFamilyChanged,
  required this.onFontSizeChanged,
  this.initialFontFamily,
  this.initialFontSize,
}) : super(key: key);
