Flutter：showModalBottomSheet底部弹出完整页面

// 弹出：商品详情信息页面voidshowInfoBottomSheet(int shopId,int goodsId){showModalBottomSheet(context:Get.context!,isScrollControlled:true,backgroundColor:Colors.transparent,isDismissible:true,enableDrag:true,builder:(context){returnContainer(height:MediaQuery.of(context).size.height*0.8,decoration:BoxDecoration(color:AppTheme.pageBgColor,borderRadius:BorderRadius.only(topLeft:Radius.circular(40.w),topRight:Radius.circular(40.w),),),clipBehavior:Clip.antiAlias,child:InfoPage(arguments:{'shopId':shopId,'goodsId':goodsId,'customCallback':(){// 关闭弹窗Get.back();// 执行确认后的业务逻辑print('用户确认了商品ID: $goodsId');showCreateOrderBottomSheet(shopId,goodsId);},},),);},);}

info页面需要接收参数和回调

import'dart:convert';import'package:flutter/material.dart';import'package:get/get.dart';classInfoControllerextendsGetxController{finalMap<String,dynamic>arguments;InfoController({requiredthis.arguments});// IDint shopId=0;int goodsId=0;// 自定义回调函数VoidCallback?customCallback;void_initData()async{shopId=arguments['shopId']??0;goodsId=arguments['goodsId']??0;customCallback=arguments['customCallback'];update(["info"]);}// 确认操作voidonConfirm(){customCallback?.call();}}
