Fix presentLimited type error on 3.8.0+

[Copilot]

Fixes #1343

PhotoManager.presentLimited() throws type '() => String' is not a subtype of type '() => int' of 'ifAbsent' on iOS.

Root cause: When presentLimited passes {'type': type.value} to invokeMethod, Dart infers Map<String, int>. The putIfAbsent callback returns a String (cancel token key), causing the type mismatch.

Fix:

• Create a Map<String, dynamic> copy before calling putIfAbsent to ensure the map accepts mixed value types

// Before: fails when arguments is Map<String, int>
arguments.putIfAbsent(PMConstants.cancelTokenKey, () => PMCancelToken().key);

// After: works with any map type
final Map<String, dynamic> args = Map<String, dynamic>.from(arguments);
args.putIfAbsent(PMConstants.cancelTokenKey, () => PMCancelToken().key);

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dart.dev
  • Triggering command: /usr/bin/curl curl -fsSL REDACTED -o /tmp/dart-sdk.zip (dns block)
• dl-ssl.google.com
  • Triggering command: /usr/bin/wget wget -qO- REDACTED (dns block)
• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
