StreamSplitButtonTheme class

Applies a split button theme to descendant StreamSplitButton widgets.

{@tool snippet}

Override the separator of regular split buttons for a specific section:

StreamSplitButtonTheme(
  data: StreamSplitButtonThemeData(
    regular: StreamSplitButtonStyle(
      separatorColor: WidgetStatePropertyAll(Colors.white24),
    ),
  ),
  child: StreamSplitButton.icon(
    leadingIcon: Icon(icons.voiceFill),
    trailingIcon: Icon(icons.caretDown),
    onLeadingPressed: () {},
    onTrailingPressed: () {},
  ),
)
