Write native code using Dart. This package liberates you from native code and low performance channel.

Still under development!!!

This is the blue part(DartNative Bridge) in the picture below:

• Support iOS & Android platform.
• Sync/Async channel with high performance.
• Generate Dart bridging code from native code.
• Automatic object marshalling between Dart and native.

Dart code:

// new Objective-C object.
RuntimeStub stub = RuntimeStub();

// Dart function will be converted to Objective-C block.
stub.fooBlock((NSObject a) {
    print('hello block! ${a.toString()}');
    return 101;
});

// support built-in structs.
CGRect rect = stub.fooCGRect(CGRect(4, 3, 2, 1));
print(rect);

Objective-C code:

typedef int(^BarBlock)(NSObject *a);

@interface RuntimeStub

- (CGRect)fooCGRect:(CGRect)rect;
- (void)fooBlock:(BarBlock)block;

@end

More ios example see: ios_unit_test.dart

Dart code:

// new Java object.
RuntimeStub stub = RuntimeStub();

// get java list.
List list = stub.getList([1, 2, 3, 4]);

// support interface.
stub.setDelegateListener(DelegateStub());

Java code:

public class RuntimeStub {

    public List<Integer> getList(List<Integer> list) {
        List<Integer> returnList = new ArrayList<>();
        returnList.add(1);
        returnList.add(2);
        return returnList;
     }

    public void setDelegateListener(SampleDelegate delegate) {
         delegate.callbackInt(1);
    }
}

Q: Failed to lookup symbol (dlsym(RTLD_DEFAULT, InitDartApiDL): symbol not found) on iOS archive.

There are two Workarounds:

1. Use dynamic library: Add use_frameworks! in Podfile.
2. Select Target Runner -> Build Settings -> Strip Style -> change from "All Symbols" to "Non-Global Symbols"
