Flutter Project Folder Structure

Flutter projects typically follow a specific folder structure that is generated when you create a new Flutter project. This structure helps organize your code, assets, and resources effectively. Here’s an overview of the common folder structure in a Flutter project:

android:

This directory contains the Android-specific code and resources for your app.

• app: Contains the main Android application code.
• gradle: Contains Gradle build configuration files.
• gradle.properties: Configuration properties for Gradle.
• gradlew: Gradle wrapper script (for running Gradle tasks).
• gradlew.bat: Gradle wrapper script for Windows.
• settings.gradle: Project settings for Gradle.

build:

This directory is auto-generated by Flutter and contains build-related files and intermediate artifacts. You can safely ignore it from version control.

ios:

This directory contains the iOS-specific code and resources for your app.

• Runner: Contains the Xcode project and configuration files.
• Podfile: Defines iOS dependencies using CocoaPods.

lib:

This is where most of your Dart code will reside.

• main.dart: The entry point for your app. This is where your app starts executing.
• You can organize your Dart code into multiple files and directories within the lib directory.

test:

Contains test files for unit, widget, and integration testing.

web:

If you plan to create a web version of your Flutter app, this directory contains the web-specific code and assets.

assets:

You can store static assets like images, fonts, and configuration files in this directory.

• By default, there’s a fonts and images subdirectory for organizing font and image assets.

pubspec.yaml:

This is a YAML file where you define your app’s dependencies (packages), metadata, and assets.

README.md:

A markdown file where you can document your project.

LICENSE:

Contains the license for your project (if applicable).

.gitignore:

Specifies files and directories that should be ignored by Git version control.

.analysis_options:

Configuration for static analysis tools.

pubspec.lock:

Automatically generated file that locks the versions of your project’s dependencies.

.metadata:

Used by the Dart analysis server for maintaining metadata about the project.

.packages:

Specifies package dependencies used in your project.

.flutter_settings:

Configuration settings for your Flutter project.

This is the basic folder structure of a Flutter project. Depending on your project’s complexity and needs, you may create additional directories and files to organize your code and resources effectively.
