This is an error message that indicates that a certain target object or value that was expected to be present in the code or program is missing or null. It could be caused by a programming error, data corruption, or an unexpected input. The code or program cannot proceed without the target object or value, and therefore throws an error. To resolve this issue, the target object or value must be located and corrected or replaced.

must not be null
"must not be null"是一个常用的错误消息,它表示某个条件或值不能为null。在Dart中,布尔类型的值只能是true或false,不能为null。因此,如果你在一个if语句或其他条件中使用了null,就会出现"Failed assertion: boolean expression must not be null"的错误。这是因为Dart的布尔类型只接受true或false,而不接受null。类似地,其他类型的对象也不能被用作布尔条件。因此,如果你试图在布尔条件中使用一个非布尔类型的值,也会出现相同的错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
