Skip add_func when function size is 0 or negative to avoid zero-sized function boundaries in IDA. Skip _miss label when PayloadAddress is 0 (invalid) and _check label when MonomorphicAddress is shared across many functions, preventing thousands of labels colliding at the same address. Tested with obfuscated app: eliminated 5206 set_name(0x0) and 5207 colliding _check labels.
Add getDartClosure to read closure's function entry point. Add getDartMap and getDartSet to read LinkedHashBase data. Handle CidClosure/CidMap/CidSet in getObjectValue switch, which previously fell through to "Unhandle class id" error.

IDA Script Fix (
DartDumper.cpp)When analyzing obfuscated apps, the generated
addNames.pyhad issues:set_name(0x0, ...)— 5206_misslabels pointed to address 0x0 becausePayloadAddress()returns 0 for functions with no code body. These all overwrote each other at address 0.set_name(0x320080, ...)— 5207_checklabels pointed to the same sharedMonomorphicAddress, overwriting each other.add_func(addr, addr)— 5206 functions had zero size (start == end), giving IDA no boundary information.Fix: validate addresses before emitting labels, skip
add_funcwhen size ≤ 0.Frida Template Fix (
frida.template.js)getObjectValue()did not handleClosure,Map, orSettypes. These fell through to"Unhandle class id"error despite having CID constants and struct offsets already exported.Added:
getDartClosure()— reads closure's function entry pointgetDartMap()/getDartSet()— reads LinkedHashBase data arrayCidClosure,CidMap,CidSetcases ingetObjectValue()switchTested with obfuscated Flutter app (Dart 3.5.4, arm64).
