Section titled “Virtual Devices”Virtual devices can be created by opening the command-palette and selecting Flutter: Select DeviceAnd selecting create android emulator. However, the performance is not Accurate and convenience is limited, therefore I recommend using a physical device.
Physical Devices
Section titled “Physical Devices”Android devices can be use for running builds by enabling USB debugging from Android developer settingsThis is done by:
- Open settings and navigate to About Phone
- Tab on the build number 7 times until a confirmation message appear
- Then enter Developer Options and enable
USB debugging - Plug the phone into the computer with USB connection
Now when selecting VSCode/command-palette/Flutter: Select DeviceThe identifier of the phone will Appear.
IDE Setup
Section titled “IDE Setup”VS Code
Section titled “VS Code”- Install the Dart extension (dart-code.dart-code)
- Install the Flutter extension (flutter.flutter-vs-code)
- Open a Dart file — the extension auto-detects the SDK
IntelliJ / Android Studio
Section titled “IntelliJ / Android Studio”- Install the Dart plugin from the marketplace
- Configure the Dart SDK path in Settings > Languages & Frameworks > Dart
Command Line
Section titled “Command Line”Use dart analyze for static analysis and dart format for code formatting:
dart analyze # static analysisdart format . # format all filesdart run # run the main entry pointdart test # run testsProject Structure
Section titled “Project Structure”A typical Dart project:
my_project/ bin/ # Entry point scripts main.dart lib/ # Library code (imported by other packages) my_project.dart test/ # Unit and integration tests my_project_test.dart pubspec.yaml # Package metadata and dependencies analysis_options.yaml # Linter and analyzer settingsCommon Pitfalls
Section titled “Common Pitfalls”- Wrong SDK path: Ensure
dart --versionworks in your terminal before configuring your IDE. - Missing pub get: Always run
dart pub getafter changingpubspec.yaml. - Conflicting SDK versions: Use
dart --versionto verify you’re on the expected Dart version across all tools.
Worked Examples
Section titled “Worked Examples”Example 1: Creating a new project
Section titled “Example 1: Creating a new project”dart create my_appcd my_appdart runExample 2: Running tests
Section titled “Example 2: Running tests”dart test # run all testsdart test test/my_test.dart # run a specific testdart test --reporter expanded # verbose outputSummary
Section titled “Summary”Setting up a Dart development environment requires the Dart SDK, an IDE with Dart support, and understanding the standard project structure. Use dart pub get to manage dependencies and dart analyze to catch issues early.
