How to create mixin class in dart language

 //

void main(){

  

//Create an instance of the class

Calculate a=Calculate();

print("Recursion of factorial:"+ a.factorial(4).toString());

print("Linear Search:"+ a.linearSearch([2,11,5,32,6,23],5));

}

// output

Result:24

Result:5

// Create Calculate class

class Calculate with LinearSearch{

  factorial(int n){

    if(n==0 || n==1){

      return 1;

    }else{

      return n*factorial(n-1);

    }

  }

  

}

//Create Linear search method using mixin class

mixin LinearSearch{

  

  // Linear search method 

    linearSearch(List<int>? list,int x){

   int i=0;

for( i; i<list!.length; i++){

       if(list[i]==x){

         print(list[i].toString());

       }

    }} }
