execute method

@override Future<NativeStepResult> execute(NativeBuildContext context, ResolvedSource source)

Execute this build step.

The context provides access to the build configuration and logger. Returns a NativeStepResult containing any artifacts produced by this step.

Implementation

  NativeBuildContext context,
