Build a Todo App With ChatGPT × Flutter : Prerequisit #
Prerequisit For Todo App By ChatGPT × Flutter : Install Flutter On Your PC #
First of all, you need to install Flutter on your PC. Please visit this flutter official page to install Flutter.
Prerequisit For Todo App By ChatGPT × Flutter : Install Merlin ChatGPT #
Next, you need to install Merlin ChatGPT on your google browser. Merlin ChatGPT is a google extension to use ChatGPT. We can use it for free, just jump to google extension page and hit the install button.
For more details, please see my another post detailed about Merlin ChatGPT.
Build A Todo App With ChatGPT × Flutter #
Now, you are all set to see the amazing magic by ChatGPT & Flutter. Let’s deep dive into the fun part now:)
1.Create a flutter project #
So first, you need to create your own flutter project to create scaffold for todo app. Open terminal and run this command to create your flutter project.
flutter create project_name
When you successfully created your project folder, let’s open the folder by VS code (any IDE is Okay).
2. Prompt Merlin GPT To Generate Codes #
This is the main part of this blog post. First, let’s open the merlin GPT and input the following prompt.
You can open merlin GPT by Cmd + M key on google browser. If you can’t call merlin GPT, please check you installed merlin on your google extension appripriately.
generate source code with flutter for todo list app
If you can successfully send your prompt to merlin GPT, you will get the source code for todo app by flutter like this.
Here's a simple example of a todo list app in Flutter:
1. Set up the project and import necessary packages.
```dart
import 'package:flutter/cupertino.dart';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
void main() {
runApp(MaterialApp(
home: HomeScreen(),
));
}
- Create a Todo class.
class Todo {
final String title;
bool isDone;
Todo({
required this.title,
this.isDone = false,
});
}
- Create a list of todos (inside StatefulWidget).
class HomeScreen extends StatefulWidget {
@override
_HomeScreenState createState() => _HomeScreenState();
}
class _HomeScreenState extends State<HomeScreen> {
List<Todo> todoList = [];
}
- Build a UI to display todos.
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Todo List'),
),
body: ListView.builder(
itemCount: todoList.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(todoList[index].title),
leading: Checkbox(
value: todoList[index].isDone,
onChanged: (bool? value) {
setState(() {
todoList[index].isDone = value!;
});
},
),
trailing: IconButton(
icon: Icon(Icons.delete),
onPressed: () {
setState(() {
todoList.removeAt(index);
});
},
),
);
},
),
floatingActionButton: FloatingActionButton(
onPressed: () {
_showAddTodoDialog(context);
},
child: Icon(Icons.add),
),
);
}
- Add a method to show an Add Todo dialog.
Future<void> _showAddTodoDialog(BuildContext context) async {
final TextEditingController _todoController = TextEditingController();
return showDialog<void>(
context: context,
barrierDismissible: false,
builder: (BuildContext context) {
return AlertDialog(
title: Text('Add Todo'),
content: SingleChildScrollView(
child: ListBody(
children: <Widget>[
TextField(
controller: _todoController,
decoration: InputDecoration(
hintText: 'Enter Todo Title',
),
),
],
),
),
actions: <Widget>[
TextButton(
child: Text('Cancel'),
onPressed: () {
Navigator.of(context).pop();
},
),
TextButton(
child: Text('Add'),
onPressed: () {
setState(() {
if (_todoController.text.isNotEmpty) {
todoList.add(Todo(title: _todoController.text));
}
});
Navigator.of(context).pop();
},
),
],
);
},
);
}
ChatGPT generated the ingredient codes for Todo App in a min:) But we are not sure how to use these ingredients.
So let me explain how to do one by one:)
3. Edit main.dart On Your Project Folder #
We will use the source code for step1, step3, step4 and step5 generaged by ChatGPT. You can copy & paste of my code as follows. Eventually, your main.dart should look like this.
import 'package:flutter/cupertino.dart';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'todo.dart';
void main() {
runApp(MaterialApp(
home: HomeScreen(),
));
}
class HomeScreen extends StatefulWidget {
@override
_HomeScreenState createState() => _HomeScreenState();
}
class _HomeScreenState extends State<HomeScreen> {
List<Todo> todoList = [];
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Todo List'),
),
body: ListView.builder(
itemCount: todoList.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(todoList[index].title),
leading: Checkbox(
value: todoList[index].isDone,
onChanged: (bool? value) {
setState(() {
todoList[index].isDone = value!;
});
},
),
trailing: IconButton(
icon: Icon(Icons.delete),
onPressed: () {
setState(() {
todoList.removeAt(index);
});
},
),
);
},
),
floatingActionButton: FloatingActionButton(
onPressed: () {
_showAddTodoDialog(context);
},
child: Icon(Icons.add),
),
);
}
Future<void> _showAddTodoDialog(BuildContext context) async {
final TextEditingController _todoController = TextEditingController();
return showDialog<void>(
context: context,
barrierDismissible: false,
builder: (BuildContext context) {
return AlertDialog(
title: Text('Add Todo'),
content: SingleChildScrollView(
child: ListBody(
children: <Widget>[
TextField(
controller: _todoController,
decoration: InputDecoration(
hintText: 'Enter Todo Title',
),
),
],
),
),
actions: <Widget>[
TextButton(
child: Text('Cancel'),
onPressed: () {
Navigator.of(context).pop();
},
),
TextButton(
child: Text('Add'),
onPressed: () {
setState(() {
if (_todoController.text.isNotEmpty) {
todoList.add(Todo(title: _todoController.text));
}
});
Navigator.of(context).pop();
},
),
],
);
},
);
}
}
It’s ok to get an error at this moment. We will create the data class accordingly:)
4. Create Todo Item Class #
After that, you can just copy & paste the source code of step2 on this blog. It’s ok if you can have the same code like this.
class Todo {
final String title;
bool isDone;
Todo({
required this.title,
this.isDone = false,
});
}
5. Run Your Code #
Now everything is ready for running your todo app! All you have to do is to save your code & hit the run button on your IDE:)
Or you can run your app from the terminal, pls run the command on your terminal!
flutter run
You should get the result like this video if everything works ok!
