Flutter HTTP软件包失败（69） [英] Flutter http package get failed (69)
问题描述
当尝试导入 http 软件包时，我看到红色的下划线是错误的。
When trying to import http package I can see the red underlining as it is error.
在终端中，我尝试运行 flutter clean ，然后将 http：^ 0.12.0添加到 pubspeck.yaml 并运行 flutter软件包获取，但显示：
无法解析URL https://pub.dartlang.org 。
pub失败（69）
In terminal I tried running "flutter clean" and then adding "http: ^0.12.0" to pubspeck.yaml and running "flutter packages get" but it shows: "Could not resolve URL "https://pub.dartlang.org". pub get failed (69)"
已正确导入 flutter / material.dart之类的软件包。不知道该怎么办。
Packages like "flutter/material.dart" are correctly imported. Don't know what to do.
这可能是 http 与flutter 1.0向后兼容的问题吗？
Could this be issue with http not being back-compatible with flutter 1.0?
