how to use string as function in dart?

Question

I am stuck in a situation where i need double doller function like in php. like:

var citis = [];

i want to use:

citis = ServiceList.mycity();

instead:

if(mycity = 'Delhi') { citis = ServiceList.Delhi();  } else
if(mycity = 'Mumbai') { citis = ServiceList.Mumbai();  }

i am sure that is possible but how, can anyone help?? Thanks in advance.

Answer 1

If it were JavaScript, you could have the string: "ServiceList." + mycity + "()" "ServiceList." + mycity + "()" and then executed it using eval function.

Use the Dart Eval package to accomplish the same thing in Dart. Take the ServiceList.mycity() function as a string and replace mycity with whichever city you want. Then, evaluate it using the package.

Answer 2

One thing you can try is to put all the cities and locations in an Key/Value Array in ServiceList and the function ServiceList.cities($city).eg ServiceList.cities('Mumbai') or ServiceList.cities('Delhi')
