最佳答案
据我所知，这是因为 modal_bottom_sheet包裹。
Flutter 中的一些更改使这个问题与空指针安全有关。它在版本 2.0.0-nullsafety.1 中得到修复.此版本引入了一些代码破坏性更改。
// Replace this
showMaterialModalBottomSheet(
context: context,
builder: (context, scrollController) {
return SingleChildScrollView(
controller: scrollController,
child: Container()
)
},
)
// With this
showMaterialModalBottomSheet(
context: context,
builder: (context) {
return SingleChildScrollView(
controller: ModalScrollController.of(context),
child: Container()
)
},
)
