Using `str | None` instead of just `str` will let the editor help you detect errors where you could be assuming that a value is always a `str`, when it could actually be `None` too.

### Classes as types { #classes-as-types }

You can also declare a class as the type of a variable.

OkHttp 3.x Change Log
=====================

## Version 3.14.9

_2020-05-17_

 *  Fix: Don't crash when running as a plugin in Android Studio Canary 4.1. To enable
    platform-specific TLS features OkHttp must detect whether it's running in a JVM or in Android.
    The upcoming Android Studio runs in a JVM but has classes from Android and that confused OkHttp!


## Version 3.14.8

_2020-04-28_

                        // have the Docker task added as a dependency. Although we control whether Docker
                        // is installed in the VM via `Vagrantfile` and we could auto-detect its presence
                        // in the VM, the test tasks e.g. `destructiveDistroTest.default-docker` are defined
                        // on the host during Gradle's configuration phase and not in the VM, so

3. Copy the file with the requirements to the `/code` directory.

    Copy **only** the file with the requirements first, not the rest of the code.

    As this file **doesn't change often**, Docker will detect it and use the **cache** for this step, enabling the cache for the next step too.

4. Install the package dependencies in the requirements file.
