EazyFlutter - VS Code Extension for Flutter Development

EazyFlutter is a powerful VS Code extension designed to streamline Flutter development by offering quick actions, intelligent widget wrappers, and useful snippets. This extension simplifies common tasks such as wrapping widgets with Consumer<T>, generating getter and setter methods, and converting JSON data into Dart models using json_serializable.

Features

Commands

• JSON to Dart Conversion - Convert JSON input into a structured Dart model with json_serializable, automatically saving it in the model folder (You can move it to your desired directory after).
• Wrap with Consumer - A quick action is available that wraps widgets with a Consumer for Provider-based state management.

Snippets

• Wrap with Consumer - Insert a Consumer<T> block instantly using a snippet.
• Generate Getters and Setters - Quickly create getter and setter methods for multiple data types, improving code efficiency.

Installation

1. Open VS Code.
2. Navigate to the Extensions Marketplace (Cmd + Shift + X / Ctrl + Shift + X).
3. Search for "EazyFlutter" and click Install.
4. The extension is now ready for use.

How to Use

Wrap a Widget with Consumer<T> (Quick Fix)

• Select a widget in your Dart file.
• Press Cmd + . (Mac) / Ctrl + . (Windows).
• Select "Wrap with Consumer".
• Enter the Provider Type, and the extension automatically wraps the widget.

Example:

Before:

Text('Hello World')

After:

Consumer<AppUserManagementProvider>(
  builder: (context, appUserManagementProvider, _) {
    return Text('Hello World');
  },
)

Using Snippets

Wrap with Consumer<T>

1. Type wrapConsumer inside your Dart file.
2. Press Tab, and it expands into:

Consumer<ProviderType>(
  builder: (context, provider, _) {
    return ChildWidget();
  },
)

3. Replace ProviderType with the actual provider class (e.g., AuthProvider).

Generate Getters and Setters

• Use snippets to create getter and setter methods for multiple data types, reducing manual coding effort.

Example:

Before:

String _name;

After using snippet:

getSetString then Enter

Result

String _name;

String get name => _name;

set name(String value) {
  _name = value;
}

JSON to Dart Conversion

1. Open the command palette (Cmd + Shift + P / Ctrl + Shift + P).
2. Search for "EazyFlutter: JSON to Dart".
3. Enter your JSON data.
4. Provide a Class name for the generated model.
5. The extension will:
   • Generate a Dart model with json_serializable annotations.
   • Save the file in lib/models/.
   • Ensure proper formatting and error handling.

Example:

Input JSON:

{
  "id": 1,
  "name": "John Doe",
  "email": "john@example.com"
}

Generated Dart Model:

import 'package:json_annotation/json_annotation.dart';

part 'user_model.g.dart';

@JsonSerializable()
class UserModel {
  final int id;
  final String name;
  final String email;

  UserModel({required this.id, required this.name, required this.email});

  factory UserModel.fromJson(Map<String, dynamic> json) => _$UserModelFromJson(json);
  Map<String, dynamic> toJson() => _$UserModelToJson(this);
}
