[Request]: Allow uri + text together in ShareParams (for iOS support)

Plugin

share_plus

Use case

Current Behavior

await SharePlus.instance.share(
 ShareParams(
  text: 'Check this out!'
   uri: Uri.parse(
    'https://example.com/page/123'
  ),
),

Results in

Invalid argument(s): uri and text cannot be provided at the same time

I see this restriction was added in https://github.com/fluttercommunity/plus_plugins/pull/3404#discussion_r2048771496 as a deliberate design choice. The discussion mentions being open to revisiting based on feedback :)

Feature request

I want to share a URL with a custom pre-filled message. Such that if a user clicks "iMessage" the custom text will be appended underneath the rich link preview.

iOS supports this natively - you just pass both to UIActivityViewController:

  UIActivityViewController(activityItems: ["Check this out!", url], applicationActivities: nil)

Proposal

Remove the restriction so iOS and make the small native code change for iOS to work. I've tested it and it works with minimal changes.

For non-iOS functionality (e.g. Android Intent.EXTRA_TEXT only has one slot ), we could either:

• Fall back to uri-only
• Concatenate them
• Document the platform difference

Beginne mit der Untersuchung der ShareParams-Validierung in share_plus und seiner plattformspezifischen Implementierungen. Verfolge anschließend, wie iOS Aktivitätselemente an UIActivityViewController übergibt. Bestätige, dass iOS sowohl text als auch uri akzeptiert, entscheide, wie nicht-iOS-Plattformen mit diesem Paar umgehen sollen, und aktualisiere Tests oder Dokumentation, um das abgeschlossene Plattformverhalten zu zeigen.
