In this branch, the function will implicitly return null which is incompatible with the type-hinted return Samsara\Fermat\Types\Base\MatrixInterface. Consider adding a return statement or allowing null as return value.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
For hinted functions/methods where all return statements with the correct type are only reachable via conditions, ?null? gets implicitly returned which may be incompatible with the hinted type.
Let?s take a look at an example:


interface ReturnsInt {
    public function returnsIntHinted(): int;
}

class MyClass implements ReturnsInt {
    public function returnsIntHinted(): int
    {
        if (foo()) {
            return 123;
        }
        // here: null is implicitly returned
    }
}

In this branch, the function will implicitly return null which is incompatible with the type-hinted return Samsara\Fermat\Types\Base\MatrixInterface. Consider adding a return statement or allowing null as return value.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
For hinted functions/methods where all return statements with the correct type are only reachable via conditions, ?null? gets implicitly returned which may be incompatible with the hinted type.
Let?s take a look at an example:


interface ReturnsInt {
    public function returnsIntHinted(): int;
}

class MyClass implements ReturnsInt {
    public function returnsIntHinted(): int
    {
        if (foo()) {
            return 123;
        }
        // here: null is implicitly returned
    }
}
