BaseStatelessWidget class

基础无状态组件 cupertino使用buildByCupertino方法构建,material使用buildByMaterial方法构建 *** 参数 1、cupertino模式:从cupertino里取对应的值,取不到则取公共参数 2、material模式:从material里取对应的值,取不到则取公共参数 3、cupertino模式下可以使用 cupertino = { forceUseMaterial: true } 强制使用material模式构建 使用 cupertino = { disabled: true } 禁止构建 4、material模式下可以使用 material = { forceUseCupertino: true } 强制使用cupertino模式构建 使用 material = { disabled: true } 禁止构建


*** Flutter禁用运行时反射,所以取值由子组件各自获取, *** cupertino模式使用 valueFromCupertino(key, value) 获取, *** material模式使用 valueFromMaterial(key, value) 获取
