Question

我有一个笔记本名称为“ paths”，我想在另一个笔记本中使用其中声明的val，但出现错误。我正在使用Spark-scala

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'TEST',
      home: DefaultTabController(
        length: 2,
        child: HomePage(),
      ),
    );
  }
}

class HomePage extends StatefulWidget {
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  List<Map<int, String>> list;

  @override
    void initState() {
      list = List();
      super.initState();
    }

  void _addList(Map<int, String> item){
    setState(() {
          list.add(item);
        });
  }

  void _removeList(int index){
    setState(() {
          list.removeAt(index);
        });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('TEST'),
        bottom: TabBar(
          tabs: <Widget>[
            Tab(icon: Icon(Icons.home),),
            Tab(icon: Icon(Icons.inbox),)
          ],
        ),
      ),
      body: TabBarView(
        children: <Widget>[
          DisplayPage(listItem: list, removeList: _removeList),
        InputPage(addList: _addList),
        ],
      ),
    );
  }
}

class DisplayPage extends StatelessWidget {

  final Function removeList;
  final List<Map> listItem;
  DisplayPage({this.listItem, this.removeList});

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemCount: listItem.length,
      itemBuilder: (BuildContext context, int index){
        return ListTile(
          // onTap: (){removeList(index);}, i can delete it in this class because it has the index
          title: Text(listItem[index][1]),
          subtitle: Text(listItem[index][2]),
        );
      },
    );
  }
}

class InputPage extends StatelessWidget {
  final Function addList, removeList;
  InputPage({this.addList, this.removeList});

  @override
  Widget build(BuildContext context) {
    return Center(
      child: Container(

        child: Row(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            RaisedButton(child: Text('ADD'), onPressed: () {addList({ 1 : 'Hello', 2 : 'World'});}),
            // RaisedButton(child: Text('DELETE'), onPressed: () {removeList();}), how to delete it from here??
          ],
        )
      ),
    );
  }
}

错误

// Find employee
$this->context->employee = new Employee();
$this->context->employee->getByEmail($email, $passwd);
$this->context->employee->logout();

请使用％run / Users / testuser / TESTParam

您还可以传递其他参数，例如

％run / Users / testuser / TESTParam $ runtype =“ Sequential” $ configuration =“ xxx” $ runnumber = 1-10
