This is interesting. What version of Flutter does it test against? |
|
@Hixie it uses BTW |
|
We ship new versions of Flutter multiple times a week. I am worried about using a mechanism that is tied to a particular version. We care about testing against the latest version. |
|
Fair point. Added Ideally at some point we can work on continuously pushing Docker image for Flutter and having up-to-date |
|
I'll be able to give this more thought after Feb 28. But I'm curious how well-trodden the Emulator/Simulator path is on Cirrus CI. This repository contains lots of Objective-C and Java code that need to be tested in either a simulated environment or real devices. Travis does not make it easy to test in emulators. |

These images can run an Android emulator. Unfortunately it won't have hardware acceleration since it's a Dockerized environment but, to my knowledge, no hosted CI has hardware accelerated emulators at the moment. Internally we have a design proposal on how to securely add such accelerated emulators but there are other priorities at the moment like adding Mac OS support. Have a great vacation and let's revisit this PR once you are back 🙌 |

Ok I've landed this and turned on Cirrus CI! Let's see how it goes! |

Cirrus CI recently added Flutter support by providing Docker images with Flutter pre-installed. It allows to avoid boilerplate of setting up an environment which makes it possible to start tests execution in a few hundred milliseconds from the moment a change is pushed to GitHub.
For this repository particularly I've seen CI times from 12 to 15 minutes for the longest part of the build (building apks). It's 2 to 3 times faster comparing to the current CI setup.
Unfortunately
flutter_plugin_toolscan't run things in parallel and take advantage of up to 8 cores that Cirrus CI can provide.Here is a build for that particular change:
I was testing Flutter support on this repository and decided to share the results. Feel free to close the PR if not interested in a better CI. Didn't want to waste my work 😅
In case you will merge the PR. Don't forget to install Cirrus CI application from Github Marketplace as described in Quick Start guide.
