mergeFlavorAssets method

ValidationResult mergeFlavorAssets(
  1. AssetConfig config
)

Merges flavor-specific assets with the main assets directory.

If a flavor is specified and the flavor directory exists, copies flavor-specific assets to the main assets directory before processing.

Parameters:

  • config: The asset configuration

Returns validation result indicating success or failure.
