Question

我想创建一个Flutter应用程序，该应用程序可以从Wordpress（WP REST API）获取最新帖子，但是运行该设备后我的设备出现红屏。我对Flutter的经验还不是很丰富，所以我希望我能在这里得到一些帮助。因为我不能在此处发布整个错误日志，因为我需要写更多的东西，所以我选择了这两行可能很有趣：

I / flutter（18219）：_ScaffoldLayout定制多子级布局委托忘记布置以下子级： I / flutter（18219）：_ScaffoldSlot.body：RenderPhysicalModel＃e87c7 NEEDS-LAYOUT NEEDS-PAINT

home_widget.dart

import 'news_widget.dart';
import 'package:flutter/material.dart';
import 'platzhalter_widget.dart';

class Home extends StatefulWidget {
 @override
 State<StatefulWidget> createState() {
    return _HomeState();
  }
}

class _HomeState extends State<Home> {
  int _currentIndex = 0;
  final List<Widget> _children = [
   NewsWidget(),
   PlatzhalterWidget(Colors.deepOrange),
   PlatzhalterWidget(Colors.green),
 ];

news_widget.dart

class NewsWidget extends StatefulWidget {
  @override
  State<StatefulWidget> createState() {
    return NewsWidgetState();
  }
}

class NewsWidgetState extends State<NewsWidget> {
  // Base URL for the wordpress site
  final String url = "https://xxxxxxxxxx.xxxx.com/";

  //api
  final String api = "wp-json/wp/v2/posts?_embed";
  // Empty list for the posts

  List posts;

  // Function to fetch list of posts
  Future<String> getPosts() async {
    var res = await http.get(Uri.encodeFull(url + api),
        headers: {"Accept": "application/json"});

    // fill the post list with results and update state
    setState(() {
      var resBody = json.decode(res.body);
      posts = resBody;
    });

    return "Success!";
  }

  @override
  void initState() {
    super.initState();
    this.getPosts();
  }
