How to use a Ternary Operator with multiple condition in flutter dart?

If you’re referring to else if statements in dart, then this ternary operator:

(foo==1)? something1():(foo==2)? something2(): something3();

is equivalent to this:

if(foo == 1){
    something1();
}
elseif(foo == 2){
    something2();
}
else something3();
