I can't see enough of your code to work out what you're doing.

At a guess, you just need to do:

public void pasteDataIntoGrid(BaseEditorGridPanel grid, BaseGridRecordDef 
recordDef, Loaded<Boolean> pasteResult) {
  readText(text -> {
    // Stick the text into your grid here
    
    // As it's now an async call, you can't return a success/fail straight 
away, so we do a callback instead
    pasteResult.data(true);
  });
}
