Dart, flutter - The argument type 'String' can't be assigned to the parameter type 'Color?'

Question

Im trying to assign a container color to a class property from a models file in dart. However it gave me an error that The argument type 'String' can't be assigned to the parameter type 'Color?'.

Here is my models file

Driver(
  name: 'Max Verstappen',
  rank: '1',
  team: 'Red Bull Racing',
  points: '182',
  color: 'Colors.blue[800]',
)

And here is the container widget

Padding(
 padding: EdgeInsets.only(left: 15),
 child: Container(
   width: 4,
   height: 50,
   color: driver.color,
 ),
),

Error

The argument type 'String' can't be assigned to the parameter type 'Color?

Answer 1

The type of a color is Color.

import 'dart:ui';

class Driver {
  final String name;
  final String rank;
  final String team;
  final String points;
  final Color? color;

  Driver({this.name, this.rank, this.team, this.points, this.color});
}

when you call it, remember to import material package on the top of your dart file to get the Colors class.

import 'package:flutter/material.dart';

final driver = Driver(
  name: 'Max Verstappen',
  rank: '1',
  team: 'Red Bull Racing',
  points: '182',
  color: Colors.blue[800],
);
