我正在开发一个项目，我正在创建选择兴趣屏幕，用户可以在其中选择 5 个兴趣。调用 API 后我开始感兴趣，然后得到 id 和 value（值是兴趣的标题），如果用户选择以下兴趣，我必须将相应的 id 发送到后端。我创建了 getData 函数来获取
List<Map<String, dynamic>> options代码：
List<Map<String, dynamic>> options = [];
void getData() async {
List<Map<String, dynamic>> tempData = [];
showDialog(
context: context,
barrierDismissible: false,
builder: (BuildContext context) {
return Center(
child: LoadingAnimationWidget.discreteCircle(
color: const Color(0XFF00B251),
size: 50,
secondRingColor: const Color(0XFFF8B32B),
thirdRingColor: const Color(0XFFF72A37),
),
);
},
);
var response = await Auth().getInterests();
Navigator.pop(context);
if (response['statusCode'] == 200) {
for (int i = 0; i < response['data'].length; i++) {
tempData.add({
'id': response['data'][i]['_id'],
'value': response['data'][i]['title']
});
}
} else {
displayErrorMotionToast(context, response['message']);
}
setState(() {
options = tempData;
});
}
@override
void initState() {
getData();
super.initState();
}
//UI CODE
Wrap(
children: options.map(
(value) {
bool isSelected = false;
if (interests.contains(value['id'])) {
isSelected = true;
}
return GestureDetector(
onTap: () {
if (!interests.contains(value['id'])) {
if (interests.length < 5) {
interests.add(value['id']);
setState(() {});
}
} else {
interests
.removeWhere((element) => element == value['id']);
setState(() {});
}
},
child: Container(
margin: const EdgeInsets.symmetric(

),

错误：
E/flutter ( 5404): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: dependOnInheritedWidgetOfExactType<_LocalizationsScope>() or dependOnInheritedElement() was called before _InterestState.initState() completed.
E/flutter ( 5404): When an inherited widget changes, for example if the value of Theme.of() changes, its dependent widgets are rebuilt. If the dependent widget's reference to the inherited widget is in a constructor or an initState() method, then the rebuilt dependent widget will not reflect the changes in the inherited widget.
E/flutter ( 5404): Typically references to inherited widgets should occur in widget build() methods. Alternatively, initialization based on inherited widgets can be placed in the didChangeDependencies method, which is called after initState and whenever the dependencies change thereafter.

理想情况下，此类任务可以使用业务逻辑和构建器方法来完成。但我们并没有生活在一个理想的世界里？
问题的解决方案就是让 UI 的第一帧先渲染。
WidgetsBinding.instance.addPostFrameCallback((_) => getData());
在初始状态下使用它。 引用自https://ankitgg66.medium.com/addpostframecallback-338316ca3207
addPostFrameCallback 方法是 WidgetsBinding 类的一部分 它继承自 Flutter 中的 SchedulerBinding。它允许 开发人员注册一个回调，该回调将在 当前帧完成渲染。回调接收时间戳 参数表示调用的时间。
