   ├── translations/ (for localizations)
   ├── fonts/ (for fonts)
   ├── scripts/ (for shell scripts)
   ├── configs/ (for JSON configurations)
   ├── raws/ (for raw files)
├── lib/
├── pubspec.yaml

With flavor

Required structure for assets folder:

<your-project>
├── <assets-folder>/
   ├── all/ <common for all flavors>
      ├── images/ (for images)
      ├── vectors/ (for vector images or svg)
      ├── translations/ (for localizations)
      ├── fonts/ (for fonts)
      ├── scripts/ (for shell scripts)
      ├── configs/ (for JSON configurations)
      ├── raws/ (for raw files)
   ├── <flavor-0>
      ├── ... (same as all/)
   ├── <flavor-1>
      ├── ... (same as all/)
   ├── <flavor-2>
      ├── ... (same as all/)
   ├── ...
├── lib/
├── pubspec.yaml

Usage

Activate the executable:

dart pub global activate resources_generator

cd into project root:

cd <your-project>

Execute the generator:

dart pub global run resources_generator:generate -i <assets-folder> -o <output-folder> -p <optional-package> -f

or execute automatically when assets changes:

dart pub global run resources_generator:monitor -i <assets-folder> -o <output-folder> -p <optional-package> -f

with:

• -i or --input, optional, is the input assets folder, default to assets.
• -o or --output, optional, is the output folder, default to lib/resources.
• -p or --package, optional, is the package name if assets is in a package/module instead of an application..
• -f or --with-flavor, optional, will generate the resource class into flavors.

Note

• For generating fonts, font file names must have this format: <family>-<attr-1>-<attr-2>.ttf, with attrs to be font style and font weight. These attrs are optional.
  Example: Roboto.ttf, Roboto-Italic.ttf, Roboto-Italic-w600.ttf

• For generating colors, all json files must have colors as file name prefix. Based on the numbers of file with this prefix, the generator will generate the suitable resource file.
  Example:

  • For single file:
    

    ├── <assets-folder>/
       ├── colors/
          ├── colors.json
    

  • For multiple files (multi variants colors):
    

    ├── <assets-folder>/
       ├── colors/
          ├── colors_dark.json
          ├── colors_light.json
