Provides a transformer that can insert environment variable values into Dart files.


Add as a dependency and as a transformer to your pubspec.yaml:

  replace_env_vars: ^0.1.0
- replace_env_vars

In your Dart code, you can mark an area for replacement by wrapping with three curly braces:

const String secretApiKey = '{{{NAME_OF_ENV_VAR}}}';

In the example above, the value of NAME_OF_ENV_VAR from your environment will replace {{{NAME_OF_ENV_VAR}}}. If you set the environment, for example using export NAME_OF_ENV_VAR="awesome", the transformer will change the code like so:

const String secretApiKey = 'awesome';
