It offers support for different host platforms: linux, mac and windows, and different devices: android and iOS.

Building

This tool is meant to be published as an AOT compiled binary distributed via CIPD.

Build the tool for different host platforms on corresponding machines. It will automatically download a suitable version of Dart to build the binary.

To create the CIPD package, make sure that the build/ folder does not exist.

Auto build

Every new commit will trigger pre-submit builders to auto build a new version for different platforms without any tag/ref.

When a new commit is submitted, post-submit builders will trigger a new version with a tag of commit_sha, and a ref of staging.

Manual build

Running tool/build.sh or tool/build.bat will build an executable binary in the build folder. Then push to cipd by running

cipd create -in build                   \
  -name flutter/device_doctor/<os>-amd64 \
  -ref <ref>                     \
  -tag sha_timestamp:<revision>_<timestamp>

• os: linux, mac, or windows.
• ref: release or staging

Note: this tool is assuming one connected device on each host, but can be easily extended to support multiple devices.
