Use Case

Users would like to be able to specify where the build artifacts are sent to outside of the standard build directory within a flutter project.

Example: automating web builds so that users can have a daily build based on business rules that are placed in a directory that a cron job checks

Proposal

Similar to what has been completed for web and aar builds, add functionality to all build commands to allow user to specify custom output directory for build artificacts.

All relevant build subcommands can be found in: https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/commands/build.dart#L24-#L44

Commands to be refactored

• BuildAarCommand
• BuildApkCommand
• BuildIOSCommand
• BuildIOSFrameworkCommand
• BuildMacOSFrameworkCommand
• BuildIOSArchiveCommand
• BuildBundleCommand
• BuildWebCommand
• BuildMacosCommand
• BuildLinuxCommand
• BuildWindowsCommand

Commands that are unable to be refactored easily ❌

• BuildAppBundleCommand – configuration for build directory is hard coded in a flutter project's android/build.gradle; additional refactoring would be necessary to pass a directory from tools cli args to grade file
