)

配置主题以及OSS

/// 初始化SharedPreferences
await SpUtil.init();
ComConfig.config(theme: AppColors.theme);
ComConfig.setOssConfig(Global.ossConfig);

static Future<Map<String, dynamic>> ossConfig() async {
  var res = await AppApi.ossToken();
  var params = {

    "dir": "appName"
    };
  return params;
}

RefreshWidget

class DemoLogic extends PagingController {
  @override
  Future<PagingResponse> loadData() async {
    // TODO: implement loadData
    dynamic result = {"current": 1, "total": 3, "records": []};
    await Future.delayed(2000.milliseconds, () {
      for (var i = 0; i < 20; ++i) {
        result["records"]?.add(i);
      }
    });

    return PagingResponse.fromMapJson(result);
  }
}

class DemoPage extends StatelessWidget {
  DemoPage({Key? key}) : super(key: key);

  final logic = Get.find<DemoLogic>();

  @override
  Widget build(BuildContext context) {
    return GetBuilder<DemoLogic>(
      builder: (controller) {
        return Scaffold(
            body: RefreshWidget(
              controller: logic,
              slivers: [
                RefreshListWidget(
                    itemBuilder: (item, index) => _buildItem(index),
                    controller: logic,
                    showList: false),
              ],
            ));
      },
      id: logic.pagingState.refreshId,
    );
  }

  Widget _buildItem(index) {
    if (index % 3 == 0) {
      return Container(
        color: Colors.deepOrange,
        width: double.infinity,
        height: 300.h,
      );
    }
