Flutter Checkbox com label

app_checkbox.dart

import 'package:flutter/material.dart';

class AppCheckbox extends StatelessWidget {
  final String label;
  final bool value;
  final ValueChanged<bool> onChanged;
  final TextStyle labelStyle;

  const AppCheckbox(
      {Key key, this.label, this.value, this.onChanged, this.labelStyle})
      : super(key: key);

  @override
  Widget build(BuildContext context) {
    return InkWell(
      onTap: () {
        onChanged(!value);
      },
      child: Container(
        child: Row(
          mainAxisAlignment: MainAxisAlignment.start,
          children: <Widget>[
            Checkbox(
                materialTapTargetSize: MaterialTapTargetSize.shrinkWrap,
                value: value,
                onChanged: onChanged,
                activeColor: Theme.of(context).primaryColor),
            Text(label, style: labelStyle),
          ],
        ),
      ),
    );
  }
}

When click label, I want to add click event handler

just add some color to the container in line 19

Here is an updated version for Dart 3.

import 'package:flutter/material.dart';

class CheckboxWithLabel extends StatelessWidget {
  final String label;
  final bool value;
  final ValueChanged<bool?> onChanged;
  final TextStyle? labelStyle;

  const CheckboxWithLabel(
      {super.key, required this.label, required this.value, required this.onChanged, this.labelStyle});

  @override
  Widget build(BuildContext context) {
    return InkWell(
      onTap: () {
        onChanged(!value);
      },
      child: Row(
        mainAxisAlignment: MainAxisAlignment.start,
        crossAxisAlignment: CrossAxisAlignment.center,
        children: <Widget>[
          Checkbox(materialTapTargetSize: MaterialTapTargetSize.shrinkWrap, value: value, onChanged: onChanged),
          Padding(
            padding: const EdgeInsets.only(left: 8.0, bottom: 2),
            child: Text(label, style: labelStyle),
          ),
        ],
      ),
    );
  }
}
