as you see in this picture it shows error when iam using this model class how to solve this problem.

I tried but it's not working.

CodePudding user response：

You are wrong syntax, replace all of yours = with : will solve problem

CodePudding user response：

the Map's key/value pairs are linked with a : not a =, so in your code instead of doing this:

key = value,

change it to this:

key: value,

and the same thing for your class.
