Error:
The argument type 'Null' can't be assigned to the parameter type 'Color'.dartargument_type_not_assignable
Type: Null
Solution:
You’re trying to send null to a parameter that expects a Colour value, which is why the problem occurs. In place of null, you can use Colors.transparent if you wish to avoid specifying a borderColor. The following is how to update your code:
AvatarImage(
imageUrl: doctor["avatar"],
bgColor: Colors.transparent,
borderColor: Colors.transparent,
),
This way, you’re providing a valid Color
value for the borderColor
parameter.
