For basic customization of PromptedChoice, you can simply set the backgroundColor and surfaceTintColor properties of the predefined promptDelegate function:

PromptedChoice<String>.multiple(
  promptDelegate: ChoicePrompt.delegatePopupDialog(
    constraints: const BoxConstraints(maxWidth: 400),
    backgroundColor: Colors.white,
    surfaceTintColor: Colors.transparent,
  ),
)

For more advanced control, you can create a custom listBuilder that can be combined with predefined options

PromptedChoice.multiple(
  listBuilder: (itemBuilder, itemCount) {
    return ColoredBox(
      color: Colors.white,
      child: ChoiceList.createWrapped(
        padding: const EdgeInsets.all(20),
        spacing: 10,
        runSpacing: 10,
      )(itemBuilder, itemCount),
    );
  },
)
