Load variables from a `.env` file into a dart-define string and copy it to your IDE Config or to the clipboard.

define_env

Load variables from a .env file into a dart-define string and copy it to your IDE Config or to the clipboard.

Usage

Get the latest version from pub:

$ dart pub global activate define_env

You can add the Pub Cache directory to execute the command easily. Learn More

Print

$ define_env      # generate dart define string and print it to stdout

You can skip printing using the --no-print flag

Copy to clipboard

$ define_env -c      # generate dart define string and copy to clipboard 

Copy to IDE

Note

• When copying to IDE config, define_env tries to preserve existing arguments and overwrites only the dart-define statements. This is not thoroughly tested and if you face problems with additional arguments please create an issue.

VS Code launch.json

$ define_env -l      # generate dart define string and copy it to launch.json

By default, all configurations in launch.json are updated. If you want to update only a specific configuration, you can do the following

$ define_env -l -n staging     # generate dart define string and copy it to "staging" configuration in launch.json

Note

• launch.json may sometimes contain comments. These comments cannot be preserved as of now. If this is important then you should avoid this package

Android Studio

$ define_env -a      # generate dart define string and copy it to all run configs

By default, all configurations in .idea/workspace.xml and .run/ are updated. If you want to update only a specific configuration, you can do the following

$ define_env -a -n staging     # generate dart define string and copy it to "staging" configuration only

Env Validation

You can add validation for your env by defining a define_env.yaml or adding a define_envsection to your pubspec.yaml

define_env:
  file_path: example
  class: MyEnv
  fields:
    <FIELD_NAME>:
      type: enum     # String | bool | int | enum
      default:       # If it is set the field in the env is optional.
      enum_values: # Defines the possible values of the enum. Required field when the type is enum.
        - value1
        - value2

Env Class Generation

Running define_env will automatically generate an Env Class for you to use in your project. The class name is defined by class and File Path is defined by file_path in define_env section of your define_env.yaml or pubspec.yaml. If you don't want a class to be generated, you can pass the --no-generate flag.

$ define_env --no-generate     # Skip Env Class generation

Roadmap

• ✅ Add support for Android Studio and Intellij.
• ✅ Add validation support to see warn if any environment variable is missing.
• ✅ Generate Config class from .env files which extract values from environment.
• ❌ Make Android Studio and VS Code extensions and plugins to update config automatically when .env files are updated.
• ❌ Copy config name directly from .env files. ex .env.staging is copied to staging config.
• ❌ Simplify command usage. ex define_env:print define_env:copy define_env:vscode etc.
