Pub get has not been run

Answer:

When you encounter the error message “pub get has not been run”, it means that the necessary dependencies for your project have not been fetched or updated.

In order to resolve this issue, you need to run the command “pub get” in your project’s root directory. This command fetches and updates the dependencies specified in your project’s pubspec.yaml file.

Here is an example to illustrate the process:

1. Create a new Flutter project or navigate to an existing one using the command line or terminal.
2. Ensure that you are in the root directory of your project.
3. Open the pubspec.yaml file.
4. Within the dependencies section of the pubspec.yaml, specify the required dependencies for your project.

dependencies:
  flutter:
    sdk: flutter
  example_dependency: ^1.0.0

5. Save the pubspec.yaml file.
6. Run the command “pub get” in your terminal.

$ flutter pub get

7. Wait for the command to complete. It will fetch and update the required dependencies.
8. Once the command finishes successfully, you can start working with your updated dependencies in your project.

By running “pub get”, you ensure that your project has all the necessary dependencies to compile and run correctly.
