I tried final String _userName but not luck, in this line:
String _userName;
And also edit this line to see if it works adding a "!" but no luck
AccountInformation(this._userName, takeInformation!)));
What can I do in that case if I want to run the app with no problems? btw, im using flutter with android studio.
Thank you in advance
CodePudding user response：
In PromoDoroClock the data type defined must be List but you are passing the _userName which is a string.
CodePudding user response：
in AccountInformation class, I guess you defined your user name as List like this:
final List username;
if you want to pass username as string type change it to:
final String username;
