Flutter is a multi-platform mobile app development framework created by Google. It allows developers to build high-quality apps for iOS and Android using a single codebase. Flutter has gained popularity in recent years due to its ease of use, fast development cycle, and strong community support.

In addition, Flutter's "hot reload" feature allows for quick iteration during development, making it a popular choice for app developers.

Open source Flutter Starter projects help developers to boost their production by providing fast and efficient starting points for new projects. They also help developers avoid boilerplate code, resulting in better quality code. Some advantages of using Flutter Starter projects include:

Saving time and effort
Improving code quality
Learning from example code
Being aware of licenses and usage restrictions

When using Flutter Starter projects, it's important to be aware of the license and any requirements for attribution or contributions.

1- Nylo

Nylo is not a starter, it is a complete micro-framework for building Flutter apps.

2- MarketKy eCommerce

MarketKy is a Free Flutter E-Commerce App Starter Template that can help you develop an E-Commerce or Market application much faster. You just need to add some adjustment to the frontend and you can create your own backend.

3- Flutter Firebase Starter project

This project is an amazing Firebase starter for your next Flutter app, it includes Firebase authentication, cloud Firestore, Firebase analytics, Firebase Crashlytics, and Firebase Storage.

4- Hungry

6- Shope - Free Flutter eCommerce Template

The “Shope” eCommerce UI Kit has the goal to help you to save time with the frontend development. You can use this template to build your apps for Android and iOS in Flutter.

The UI Kit includes all resources you need to reuse the components, it includes 38 screens, assets, icons, and fonts.

8- Flutter Starter

Flutter Starter, as the name suggests, is a starter kit for Flutter that helps you bootstrap projects with all the essential modules like State Management, API calls, Style Guide, etc. It helps you build production ready apps in a jiffy. Handle everything at one place, so you don't have to rewrite code.

Features Highlight

Folder Structure: Flutter Starter comes with a well-defined folder structure. Devs can easily navigate it and add files where necessary.
Style Guide: This kit helps you to build a Style Guide for your app. You can add your image and font assets, splash screen, color constants and theme data. These are available for use wherever required in your project.
API Calls: The starter kit includes all the files you need for API handling. You can choose from REST, GraphQL and Firebase depending on your project.
State Management: Flutter Starter contains all the state management files, models and repositories for your app. We will use Bloc for state management.
Routers & Dependencies: This kit allows you to quickly add routers for your app screens. Dependencies can also be added to your app by simply copy-pasting the installation version from pub.dev into the designated file.
Testing & Deployment: Lastly, you can test and deploy your app smoothly using Flutter Starter! Go to the test folder, add your test files and start writing test cases. Check out the Android or iOS pages to deploy your app.

9- Flutter Boilerplate

This is a simple boilerplate template for creating a production-ready Flutter app with icon/ splash screen generation, rest boilerplate, and reporting (analytics, performance, and crash reporting) all wired up for you.

10- Starter app

The focus of this starter app is thus not on the UI or functionality, but rather to show how a set of typical app functionalities can be developed and supported in a sound code structure. The app structure has also been designed to support a development team through separation of concerns and sound abstractions, as well as support for all layers of testing (unit, widget, and integration).

Features

Support for iOS, Android, and web
Separation of business logic in models and providers, and UI in a separate folder structure
Use of provider for app state management
Authentication and authorization using OAuth2
State management of login and login token including permanent storage for restarts
Simple widget framework for handling logged-in, expired, and logged-out states
Basic UI with sliding drawer menu and menu options
Testing using unit test framework and mocking
Integration tests
Localization using i18n and the built-in Flutter support for generating boilerplate
Use of a global UI theme
Custom icons for both iOS and Android
Use of Firebase Analytics for usage tracking
Use of Firebase Crashlytics for crash reporting
Use of Firebase Cloud Messaging for push notifications
Use of a OS native capability (location tracking) using a published plugin (geolocator)
Use of Google Maps to present a map of the current location
Use of an independently defined new widget type called AnchoredOverlay to overlay a map widget.

11- Flutter Template UI

This repository contains several basic UI templates accompanied by quite a lot of notes in the hope that you can understand the code made in them, besides that there are also several implementations of certain packages/libraries in them.

This repository is very useful for new Flutter developers to understand more or less the usage of widgets in some conditions, besides that not only widgets but also there are examples of implementing modeling which is very helpful later if you want to call API.

Feel free to use this template with the hope that many new Flutter developers will be helped and become even happier with making applications using Flutter. All the templates here are made with the Flutter cli, and have also been created without any issues in them that have been analyzed with the Flutter Analyze function.

12- Supbase Starter

This example will set you up for a very common situation: users can sign up with a magic link and then update their account with public profile information, including a profile image.
