Pull request overview

This PR updates the Flutter plugin's download URL template to use a dynamic extension placeholder instead of a hardcoded .zip extension, aligning it with how other runtime plugins handle different archive formats across operating systems.

Changes:

• Modified the url_template in Flutter plugin configuration to use {{.Extension}} instead of hardcoded .zip

Comments suppressed due to low confidence (1)

plugins/runtimes/flutter/plugin.yaml:9

• The ExtensionConfig struct only supports 'windows' and 'default' fields. The 'linux' field will be ignored by the GetExtension function, which only checks for 'windows' and falls back to 'default' for all other OSes. Either the ExtensionConfig struct needs to be updated to support OS-specific extensions beyond Windows, or the linux entry should be removed and default should be set to 'tar.xz' if that's the intended extension for all non-Windows platforms.

  extension:
    default: "zip"
    linux: "tar.xz"

Missing space between 'Flutter' and 'runtime'. Should be 'Dart Flutter runtime'.
