Dart const 构造函数 - 它可以是默认的吗？

Question

Why can't const be inferred, if we get warnings from Lint to use it? Why, if possible, all classes constructors aren't by default const? This would let our code much more clean.

Answer 1

The main point of using const is not to assist the compiler in optimizations but to protect yourself from mistakes which means it prevents you from inadvertently modifying something you didn't expect to be modified.

Generally it makes it easier to program a when there is too many variables you dont. No need to memorize which one should be modified and which one shouldn't.
