扑来 - 更改TextField自动完成位置
我正在使用Flutter的自动完成，但我想将其显示在Textfield上方。这可能吗？
这是基本设置：
Autocomplete<String>(
optionsBuilder: (TextEditingValue textEditingValue) {
if (textEditingValue.text == '') {
return const Iterable<String>.empty();
}
if (textEditingValue.text.contains('...')) {
return widget.myBloc.names
.where((String option) {
return option.contains(
textEditingValue.text.toLowerCase());
});
} else {
return const Iterable<String>.empty();
}
},
onSelected: (String selection) {
log('selection -> $selection');
},
optionsMaxHeight: 40,
fieldViewBuilder: (context, controller, focusNode,
onEditingComplete) {
return TextField();
}
)
I'm using Flutter's Autocomplete but I would like to have it display above the TextField. Is this possible?
Here's the base setup:
Autocomplete<String>(
optionsBuilder: (TextEditingValue textEditingValue) {
if (textEditingValue.text == '') {
return const Iterable<String>.empty();
}
if (textEditingValue.text.contains('...')) {
return widget.myBloc.names
.where((String option) {
return option.contains(
textEditingValue.text.toLowerCase());
});
} else {
return const Iterable<String>.empty();
}
},
onSelected: (String selection) {
log('selection -> $selection');
},
optionsMaxHeight: 40,
fieldViewBuilder: (context, controller, focusNode,
onEditingComplete) {
return TextField();
}
)

我发现了一下，但是您不喜欢答案...
在flutter图书馆中/widgets/autocomplete.dart#l367“ rel =“ nofollow noreferrer”>在Rawautocomplete实现的第367行上，他们对其对齐方式进行了硬编码以跟踪
textfield的textfield。我只能在复制其整个实施后才能绕过此操作，并执行以下操作：targetandanter：alignment.topleftfolloweranchor：alignment.bottomleft.bottomleftOptionViewsBuilderwherever you decide to implement it,I figured it out, but you're not gonna like the answer...
In the Flutter library, on line 367 of the RawAutocomplete implementation, they hardcoded its alignment to track the bottom left of the
TextField. I was able to circumvent this only after copying their entire implementation, and doing the following:targetAnchor: Alignment.topLeftfollowerAnchor: Alignment.bottomLeftOptionViewsBuilderwherever you decide to implement it, shown here in the material Autocomplete implementation, change toalignment: Alignment.bottomLeft.
