Cannot convert null literal to non-nullable reference type.

Nullability of reference types in return type of 'Task<string> ClipboardImpl.GetTextAsync()' doesn't match implicitly implemented member 'Task<string?> IClipboard.GetTextAsync()'.

Nullability of reference types in type of parameter 'text' of 'Task ClipboardImpl.SetTextAsync(string text)' doesn't match implicitly implemented member 'Task IClipboard.SetTextAsync(string? text)' (possibly because of nullability attributes).

Nullability of reference types in return type of 'Task<object> ClipboardImpl.GetDataAsync(string format)' doesn't match implicitly implemented member 'Task<object?> IClipboard.GetDataAsync(string format)'.

Nullability of reference types in type of parameter 'value' of 'void WindowBaseImpl.PositionChanged.set' doesn't match implicitly implemented member 'void IWindowBaseImpl.PositionChanged.set' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'value' of 'void WindowBaseImpl.Deactivated.set' doesn't match implicitly implemented member 'void IWindowBaseImpl.Deactivated.set' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'value' of 'void WindowBaseImpl.Activated.set' doesn't match implicitly implemented member 'void IWindowBaseImpl.Activated.set' (possibly because of nullability attributes).
