A better way to override default error messages and error schemas

[bitterteriyaki]

Currently, there is no a good way to override the default error messages and schema. For example:

{
  "username": [
    "This field may not be null."
  ],
  "email": [
    "This field is required."
  ],
  "password": [
    "This field is required."
  ]
}

This above is the default error messages and schema, I want to change it to look like the following:

{
  "details": [
    "username field may not be null",
    "email field is required",
    "password field is required"
  ]
}

As long that I searched, there is no a good and native way to do this. What do you guys think about it?
