how to use ternary if else with two or more condition using \"OR\" and \"AND\" like

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

(foo==1)? something1():(foo==2)? something2():(foo==3)? something3(): something4();

is equivalent to this:

if(foo == 1){
    something1();
}
elseif(foo == 2){
    something2();
}
elseif(foo == 3){
    something3();
}
else something4();
