Konflikt zwischen Ort und url_launcher Plugin

Question

Ich entwickle eine App, die Punkte von Interesse rund um den Standort des Benutzers findet. Um den Standort des Benutzers zu erhalten, verwende ich das location Plugin, das ganz nett funktioniert.
Die nächste Sache, die ich implementieren möchte, ist eine Schaltfläche, um die Standard-Mapping-Anwendung zu öffnen, um den Benutzer zum POI zu navigieren. Ich ging mit dem Plugin url_launcher und dem geo: url-Schema für Android und die Karten: Schema für iOS.
Unabhängig voneinander funktionieren beide Plugins wie erwartet. Sobald ich beide Plugins in meinem Projekt hatte, begannen die Probleme. Unter Verwendung der Standardeinstellungen von flutter create ich die folgende Fehlermeldung erhalten:

Launching lib/main.dart on iPhone 6 in debug mode... 
Running pod install...

[!] Pods written in Swift can only be integrated as frameworks; add `use_frameworks!` to your Podfile or target to opt into using it. The Swift Pod being used is: location

So weit so gut. Hinzufügen von use_frameworks! in einem anderen Fehler führte zu meinem podfile, wie sie in der Fehlermeldung vorgeschlagen:

“Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.

Could not build the application for the simulator.

Leider habe ich keine Ahnung, wie von hier gehen. Kann mir jemand helfen, das zu klären?

Hinweis
Dieses Problem tritt nur unter iOS auf. Beide Plugins funktionieren wie ein Zauber auf Android.

Answer 1

Schnelle Plugins erfordern use_frameworks! und das wird noch nicht vollständig unterstützt.

Ich bin currently working darauf. Danke für Ihre Geduld!
