你会如何规避这个问题？

名称'Colors'在库'colors.dart'和'v3.dart'中定义.

冲突的包裹:

• import'package:flutter/material.dart';
• import'package:googleapis/calendar/v3.dart';

Flutter，谷歌日历 API v3 https://pub.dartlang.org/packages/googleapis

作品：

  Future<List<Event>> getEvents() =>
  calendarApi.events.list("primary",
  )
  .then((Events events){
    return events.items;
  }).catchError((e){
    print("error encountered");
    print("${e.toString()}");
  });

不起作用：

DateTime start = new DateTime.now().subtract(new Duration(days: 10));
DateTime end = new DateTime.now().add(new Duration(days: 10));
..
  Future<List<Event>> getEvents() =>
  calendarApi.events.list("primary",
    timeMin: start,
    timeMax: end,
  )
  .then((Events events){
    return events.items;
  }).catchError((e){
    print("error encountered");
    print("${e.toString()}");
  });

为什么？

我已经浏览了很多关于这个确切问题的论坛帖子,但我还没有找到解决方案.

应用程序在本地工作但不在Heroku上工作.

我错过了什么?? !!
