better_protoc_plugin

skip better_protos on google protos; v1.2.2

• Skip better_protos on Google protos because they don't play nice for some reason. Achieved by ensuring the package name does not contain google. TODO: Maybe add a skip file or package level option in the future.

• Remove extra annoying print.

• Dart_options are gone! Pass only a single better_protos option to protoc!

• Actually generate dart:core DateTime and Duration getters/setters

• Add @override prefix to enum value field

• New .proto file-level experimental options (all default to false):
  • generate DateTime / Dart Duration getters/setters and autoconvert these <-> google.protobuf.Timestamp / google.protobuf.Duration:

    option (dart_options.use_date_time) = true | false;
    

  • generate nullable optionals (Type? vs Type):

    option (dart_options.nullable_optionals) = true | false;
    

  • generate abstract interface classes (prefixed with 'I') for messages:

    option (dart_options.message_interfaces) = true | false;
    

• generate abstract interface class for each message prefixed with 'I' by default
• use real Dart enums + unit test
• enum values now use lowerCamelCase + unit test
• upgrade to Dart 3 SDK
• remove unnecessary ignore rules and @dart = 2.12 version directive
