我想把 Bottom Sheet 放在一个独立函数中，但没有找到该怎么安排。所有例子都是把 Bottom Sheet 放进函数里，可不可以定义一个共用的 Bottom Sheet 函数，然后在其他地方再次调用？
I'd like Bottom Sheet in its own separate function, but haven't found how to arrange that. All the examples put Bottom Sheet inside a function, yet could I define one shared Bottom Sheet function and call it again from other places?
共用的 showModalBottomSheet 需要你传入当前的 context，例如
void openSharedSheet(BuildContext pageContext) {
showModalBottomSheet(
context: pageContext,
builder: (sheetContext) {
return Text("Shared bottomSheet");
},
);
}更多 showModalBottomSheet 说明 (https://api.flutter.dev/flutter/material/showModalBottomSheet.html)
A shared showModalBottomSheet requires you to supply the current context, for example
void openSharedSheet(BuildContext pageContext) {
showModalBottomSheet(
context: pageContext,
builder: (sheetContext) {
return Text("Shared bottomSheet");
},
);

可以。定义一个共用的 showModalBottomSheet 函数，用 child 参数传入你想显示的视图
///
/// Open the shared modal sheet
///
Future<R?> openSharedModal<R>({
required BuildContext pageContext,
required Widget content,
bool? scrollControlled,
ShapeBorder? borderShape,
bool dismissible = true,
}) {
return showModalBottomSheet<R>(
isDismissible: dismissible,
context: pageContext,
elevation: SheetSettings.elevation,
barrierColor: SheetPalette.barrier,
isScrollControlled: scrollControlled ?? true,
enableDrag: true,
backgroundColor: SheetPalette.modal.ofContext(_pageContext),
shape: borderShape ?? SheetSettings.borderShape,
builder: (BuildContext sheetContext) {
return content;
},
);
}Yes. Define a shared showModalBottomSheet function, with a child parameter carrying the view you want
///
/// Open the shared modal sheet
///
Future<R?> openSharedModal<R>({
required BuildContext pageContext,
required Widget content,
bool? scrollControlled,
ShapeBorder? borderShape,
bool dismissible = true,
}) {
return showModalBottomSheet<R>(
isDismissible: dismissible,
context: pageContext,
elevation: SheetSettings.elevation,
barrierColor: SheetPalette.barrier,
isScrollControlled: scrollControlled ?? true,
enableDrag: true,
backgroundColor: SheetPalette.modal.ofContext(_pageContext),
shape: borderShape ?? SheetSettings.borderShape,
builder: (BuildContext sheetContext) {
return content;
},
);
