Flutter: The named parameter 'height' isn't defined-CodePudding

I am learning Flutter and I'm very beginner to it. In my application i create a custom button:

import 'package:flutter/cupertino.dart';
import 'package:flutter/src/widgets/container.dart';
import 'package:flutter/src/widgets/framework.dart';
import 'package:fruits_market/core/constants.dart';
import 'package:flutter/material.dart';

class CustomGeneralButton extends StatelessWidget {
  const CustomGeneralButton({super.key,this.text});
  final String? text;

  @override
  Widget build(BuildContext context) {
    return Container(
      decoration: BoxDecoration(
        color: KMainColor,
        borderRadius: BorderRadius.circular(8), 
        height: 60,
        width: 100,
        ),
      child: Center(
        child: Text(
          text!,
          style: TextStyle(
            fontSize: 14,
            color: const Color(0xffffffff),
            fontWeight: FontWeight.w500,
          ),
          textAlign: TextAlign.left,
          ),
      ),
    );
  }
}

I got this error :

The named parameter 'height' isn't defined

this error appears also with the 'width' property. How to fix it?

CodePudding user response：

BoxDecoration can't use height and width, you need to set this to the Container.

 Container(
    height: 60,
    width: 100,
    decoration: BoxDecoration(
       color: KMainColor,
       borderRadius: BorderRadius.circular(8), 
    ),
  ....
);
