I read the other related errors and I have been unable to fix my problem
Please help me!
It is the common Expected expression in list of expression error.
Furthermore, I want to know if my error is connected to appdelegate.swift file.
Change
selector(MPCBrowser.requestFoundPeers(_:))
to:
#selector(MPCBrowser.requestFoundPeers(_:))
You forgot the # symbol that precedes selector in #selector.

My Android project in Xamarin keeps failing to build due to below error
invalid symbol :"default" default.png res/drawable/default.png
not sure what is causing this to happen.
Any help will be greatly appreciated.
Thanks

default is c# keyword, you need rename your picture's name.
As mentioned before default is the keywords and that why it's failing . I wanted to share the lists so you may save your time by not using other keyword . We have quite a large number of keywords in c#:
Please find the few list mentioned in link below:

So if u use any of the reserved names u may come across this kind of error.
I have a problem with a code snippet I tried to play with, and since I am new to dart I don't really understand the error message. Can somebody explain to me why the error message says
The constructor returns type 'dynamic' that isn't of expected type
'widget'.
and how to fix it?
The class MaterialList doesn't exist. It looks like maybe you meant TwoLevelList, which is deprecated. You should try ListView instead.
If you have other import statements try to use alias as some libraries may be the reason for conflict.
Example: import 'package:html/parser.dart' as parser;
When doing many different (obviously) wrong things in A++ syntax I only get "Syntax error" in Description and some number (Err:9999) in Diagnostic ID. This does not help me at all finding out whats wrong so I can fix it. No hint, no nothing!
This is compile time syntax errors that the IDE should just hand to me.
So how can I get more detailed information about what is wrong?
When you doubleclick on a syntax error line in the compiler output window, the code editor window opens and displays the code with the syntax error. The part of the code with the error is marked with a red squiggly underline and the cursor is placed at the start of the syntax error. This should make it easy to find out what is wrong.
In addition to what j.a.estevan suggested, in my experience syntax errors also occur because
you forget the second = symbol in the where part of a select statement
you unintentionally add a second = symbol when assigning the value of a variable
you delete a variable in the classDeclaration of a class/form, but it is still used in one of the methods
a macro is changed/deleted
an object is changed/deleted and the cross references were not up to date or not checked
There is no way of showing more information that this "Syntax error" for that error type. Almost always is a missing semicolon or brackets dispaired.
This statement:
new NumberFormat("#.##").format(12.33)
throws this error:
"Class 'double' has no instance method '&'"
Is it a bug or am I doing something wrong?
This is probably a known issue: https://code.google.com/p/dart/issues/detail?id=9215
I guess you don't need to worry about it, it should be fixed soon.
I have noticed quite a few times that syntax errors like
Exit(push(ASBDD(asPixmap, _ScriptSavePixmap(Script, PMRGBAdjust(_ScriptGetPixmap(Script, Args[0].Index), adjparams))));
actually compiles. Notice that one closing bracket ) is missing. (Of course it also compiles if I add this missing bracket!)
Is this a documented feature?
Additional info: The statement in question is the last statement in a code block. Inserting any statement after this statement will cause the compiler to report the correct missing ")" error.
It would appear that the compiler loses track of the missing ")" error when it encounters the end of the block. This is most likely a compiler bug. It seems likely to me that this anomaly has been around for a long time. Don't rely on it.
