Copy/paste messes up correctly formatted code

[abarth]

Steps to Reproduce

1. Open a dart file in a Flutter project.
2. Copy the following to the clipboard:

  double estimateScrollOffsetExtent({
    int firstIndex,
    int lastIndex,
    double leadingScrollOffset,
    double trailingScrollOffset,
  });

3. Paste into the body of a class declaration.
4. Notice that you get the following text:

  double estimateScrollOffsetExtent({
  int firstIndex,
  int lastIndex,
  double leadingScrollOffset,
  double trailingScrollOffset,
  });

The pasted text has removed two spaces of indent each from lines 2 through 5.

Cannot reproduce.

@alexander-doroshko Is there a preference that might affect this? Or could it be fixed in the current dev sources? (2017.1 EAP)

I do see this in 2016.3.3 (dart plugin 163.11306).

This is an abstract method with optional parameters, right? Yes, looks like Dart plugin has a bug with multiline optional parameters formatting. Please file it n our tracker.

Workaround 1: use Paste Simple (Cmd+Alt+Shift+V) instead of standard Paste.

Workaround 2: change Reformat On Paste option in Preferences | Editor | General | Smart Keys (default is Indent Each Line).

Thanks!

I've published the Dart plugin with the fix for IntelliJ IDEA 2016.3.x. You should get a suggestion to update the plugin or try Help | Check for updates.

Thanks for the quick update @alexander-doroshko !

I confirmed that paste works correctly for this example with all four "Reformat on paste" settings.
