Hi sir, I got 2 error :
The getter 'length' isn't defined for the type 'Object'.
Try importing the library that defines 'length', correcting the name to the name of an existing getter, or defining a getter or field named 'length'.

A value of type 'Object?' can't be assigned to a variable of type 'List<dynamic>'.
Try changing the type of the variable, or casting the right-hand type to 'List<dynamic>'.
