Dynamic request class injection in laravel

I have a custom request class which is getting longer and longer with project development.

An API endpoint is expected to have multiple types ofinput. Any one is expected to be received at once.

According to the input, the validation rules are being constructed.

Right now I am having a long list of swith-cases to construct validation rules.

I want to create multiple requests classes for each case and dynamically inject appropriate request class to the controller method. Note that I cannot create multiple api endpoints.

Is there any good suggestion to handle this?

This sounds like what you are after. The example shows how the class is dynamically resolved :)

/**
     * Get the sub class name with namespace
     * @return string
     */
    public function getRequestClass()
    {
        return '\<path>\<to\<namespace>\' . studly_case($this->resourceType) . 'Request';
    }

Is it just me or does this seem like it's what dependency injection is supposed to be for?
