Google's Flutter Tutorials | 1- Flutter Project Structure | Android, iOS, Web & Desktop | Dart

In this video we will learn about flutter project structure.
Android and iOS directories hold a complete Android and iOS app respectively, with all their respective files. Whenever you want to implement any platform specific feature you can implement it by going in these directories.
1. lib directory
The lib directory holds all your dart code used to run your app.
2. pubspec.yaml
pubspec.yaml is a special file. It contains your app name, description, SDK version, dependencies, and other important stuff.
3. test directory
The test directory is for writing tests in dart similar to instrumented tests in Android using Espresso.

The Files and Folder that we mainly don’t touch
In 99.99% of cases, we don’t touch these files. As manually edit them can destroy the entire project (expect .gitignore, and README.md ?).

4. .idea directory holds all project specific settings. Settings are stored mainly in the form of XML files. We normally don’t touch these folders.

5. The .gitignore file is a text file that tells Git, which files or folders to ignore in a project.

6. .metadata, .packages, pubspec.lock are generated by flutter itself. These files are used by the framework itself for internal usages. We normally don’t touch them. As they perform internal tasks.

7. README.md is a markdown file mainly used in version control like Git for representing information of other files.
