Acquire protoc:

wget https://github.com/protocolbuffers/protobuf/releases/download/v3.10.1/protoc-3.10.1-linux-x86_64.zip
unzip protoc-3.10.1-linux-x86_64.zip

Install the protoc plugin for dart:

flutter pub global activate protoc_plugin

You must have 3 items on your path now:

• protoc
• dart (this will be installed in your flutter/bin/cache/dart-sdk)
• your flutter pub bin (flutter/.pub-cache/bin)

To compile:

protoc -I=. --python_out=../etl/dadguide_proto enemy_skills.proto
# Change this path to match your installation
protoc -I=. --dart_out=../../../AndroidStudioProjects/dadguide2/lib/proto/enemy_skills/ enemy_skills.proto
