Dart Code Generator #

A command-line tool which generates Dart code for Protobuf type registries.

Usage #

The generator accepts several command-line arguments:

Required option --descriptor specifies the path to a file which contains a google.protobuf.FileDescriptorSet. The descriptor set contains all the Protobuf types for which the tool must generate code.
Required option --destination specifies the path to the file into which the code must be written. If the file does not exist, it is created.
Option --standard-types specifies a Dart package which contains standard Protobuf types. The default value of this option is spine_client. The package should contain types:
- declared in the google.protobuf.* package;
- declared in the base module in Spine.
Option --import-prefix specifies the path prefix for .pb.dart files generated for types listed in the descriptor. Defaults to an empty path, implying that the generated files are located in the same directory as the destination.
Flag --stdout makes the tool print the output Dart code into the standard output stream, as well as writing it into the destination file.
Flag --no-stdout ensures that the tool does not print Dart code into the standard output stream. This is the default behaviour.
Flag --help (or -h for short), makes the tool print a brief usage guide. When called with this flag, all the other flags are ignored.
