How can i chose my icon based on a string

Question

I am getting a lot of strings whos' names are those of icons. If I try to create and Icon with a string as name

Icon(
   Icons._transactionType
)

I get 'the getter _transactionType is not defined for for the class 'Icons''.

That is all the ideas I had so far, and also the flutter docs for icon and icons didn't help.

As of now i have hardcoded the icons in, but since i am now storing them in .json, i can only save them in strings, and i want to avoid a method that goes through all icons and choses the one i need.

Here you see it working now, and i want to get the icon istead of with 'Icons.train' with 'Icons._transactionType'

One way is to create a map

Map<String, IconData> iconMapping = {
 'train' : Icons.train,
 'airplane' : Icons.airplanemode_active,
 ...
};

and while using, instead of Icon(Icons._transactionType) use Icon(iconMapping[_transactionType])
