在Flutter开发中,避免在生产代码中使用print是一个常见的最佳实践。这是因为print语句会将日志信息输出到控制台,这在开发调试阶段非常有用,但在生产环境中可能会泄露敏感信息,或者产生不必要的性能开销。为了在生产环境中记录日志,应该使用专门的日志记录框架。以下是如何在Flutter中替换print语句为日志记录框架调用的详细...
警告:Don't invoke 'print' in production code. 翻译:不要在生产代码中调用“print”。 原因: avoid_print规则要求:在线上代码中应该避免使用 print。上面示例没有执行这个规则,所以报上面警告。 解决办法: (1)(推荐)使用debugPrint替换即可: debugPrint('Hello World!'); (2)如果不想按规范替换,则在analysis...
What you don’t need is to provide a way to inject a mock channel into your production code. 上面的两个例子都在单元测试中声明了channel对象。这工作得很好——除非你担心重复的通道名称和编解码器——因为所有具有相同名称和编解码器的通道对象都是等价的。你可以通过将channel声明为const,使其对生产代码...

Relational— these are the databases in the traditional sense. They don’t just store data but also therelationshipsbetween the data. SQLite is an example of a relational database. 关系式-这些是传统意义上的数据库。 它们不仅存储数据,还存储数据之间的关系。 SQLite是关系数据库的一个示例。
