// This sample uses Baidu Maps as the base Map SDK to demonstrate how to integrate the Tencent Cloud IM Flutter LBS plug-in.
// This sample mainly introduces how to inherit the three abstract classes of tim_ui_kit_lbs_plugin according with the selected Map SDK selected.
// Including: TIMMapService/TIMMapWidget/TIMMapState.
// And demonstrate how to call these UI widgets with these three inherited classes.
// Including: location selector (LocationPicker) / location message full display (LocationShow) / location message list display (LocationMsgElement)
// 本Sample以百度地图为底层SDK演示如何使用腾讯云IM Flutter LBS能力插件
// 有关如何快速集成本插件与百度地图Flutter SDK，请参考此文档：https://docs.qq.com/doc/DSXRBZG1CUGhIVEZx
// 本Sample主要介绍如何根据选定地图SDK继承tim_ui_kit_lbs_plugin的三个抽象类
// 分别为：TIMMapService/TIMMapWidget/TIMMapState
// 并演示如何将实例化后的三个类，传入LBS组件中，实现三个功能组件
// 分别为：位置选择器（LocationPicker）/位置消息完整展示器（LocationShow）/位置消息列表展示器（LocationMsgElement）
