基于SharedPreferences的脚手架ThemeData设置的最佳方法

import 'package:shared_preferences/shared_preferences.dart';

Future<void> saveThemeData(ThemeData themeData) async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  await prefs.setInt('themeColor', themeData.primaryColor.value);
}

Future<ThemeData> getThemeData() async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  int themeColor = prefs.getInt('themeColor') ?? Colors.blue.value;
  return ThemeData(primaryColor: Color(themeColor));
}

// 设置ThemeData
ThemeData themeData = ThemeData(primaryColor: Colors.red);
await saveThemeData(themeData);

// 获取ThemeData
ThemeData savedThemeData = await getThemeData();
