Where to find ROS2 Dashing geometry2/tf2 documentation?

I am trying to port this wheel encoder function to ROS2 Dashing using geometry2/tf2, but the only guides that I have found are either for the wrong ROS version or only explain command-line usage.

The documentation explaining a wrong version is calling tf2_ros::TransformBroadcaster without arguments:

static tf2_ros::TransformBroadcaster br;

But tf2_ros::TransformBroadcaster() for Dashing is expecting 3 arguments, as shown here:

  template<class NodeT, class AllocatorT = std::allocator<void>>
  TransformBroadcaster(
    NodeT && node,
    const rclcpp::QoS & qos = rclcpp::QoS(100),
    const rclcpp::PublisherOptionsWithAllocator<AllocatorT> & options =
      rclcpp::PublisherOptionsWithAllocator<AllocatorT>())

Where to find developer documentation for geometry2 on ROS2 Dashing?

You should look to the test files for an example implementation (https://github.com/ros2/geometry2/tre...), not in the class definition.

Do you have a specific solution?

A specific solution for what?

At the moment, there is no documentation for the tf2 package in ROS2. But the implementation is very similar to ROS1.

Some examples for using the tf2 broadcaster:

You don't need any arguments for the tf2_broadcaster.
