[英]Importing a top-level member of a library in Dart
What is the Dart equivalent of the following Python syntax for importing just a part of a module? 仅导入模块一部分的以下Python语法的Dart等效项是什么? This imports just urlopen
from the urllib2
module. 这仅从urllib2
模块导入urlopen
。
from urllib2 import urlopen
To import only a part of a library, you can do the following. 要仅导入库的一部分,可以执行以下操作。 This imports only foo
and bar
: 这仅导入foo
和bar
:
import 'package:lib1/lib1.dart' show foo, bar;
And this imports everything except foo
: 这将导入除 foo
外的所有内容:
import 'package:lib2/lib2.dart' hide foo;
