轮播滑块错误'firstIndex == 0 || childScrollOffset(firstChild!)! - 滚动偏移<= precisionErrorTolerance

Question

                    Column(
                      children: [
                        if (state.bumperBountyData.isNotEmpty)
                          CarouselSlider(
                            items: state.bumperBountyData.map((e) {
                              return Container(
                                height: 200,
                                color: Colors.red,
                              );
                            }).toList(),
                            options: CarouselOptions(
                              enableInfiniteScroll:
                                  state.bumperBountyData.length > 1,
                              viewportFraction: 0.85,
                              onPageChanged: (index, reason) {
                                state.bumperBountyCurrentIndex = index;
                                state.update([
                                  ProductBySectionController
                                      .bumperBountyListUpdate
                                ]);
                              },
                              aspectRatio: 1.3,
                              pauseAutoPlayOnTouch: true,
                              enlargeCenterPage: false,
                              disableCenter: false,
                              padEnds: !(state.bumperBountyData.length > 1),
                              autoPlay: state.bumperBountyData.length > 1,
                            ),
                          ),
                      ],
                    ),

CarouselSlider 工作得很好，但调试控制台中不断弹出错误。

════════渲染库捕获异常 ═════════════════════════════════ 'package:flutter/src/rendering/sliver_fixed_extent_list.dart': 失败 断言：第 338 行 pos 12：'firstIndex == 0 || childScrollOffset(firstChild!)! - 滚动偏移<= precisionErrorTolerance': is not true.

我认为旋转木马滑块位于柱内是

的原因

错误。如果删除该列，错误就会消失，或者您可以将

带有扩展或灵活小部件的轮播滑块，或者您可以用

包裹它

SizedBox 并指定其高度。
