Memory allocated in Golang by C.CString() should be freed

Line 422 in 5022edb

*jsonResponse = C.CString(string(respB))

A function should be provided to be called by flutter/dart, to release the memory allocated by C.CString()

//PLGNFreeCString frees the memory allocated by Golang(using C.CString() ) for the given C string.
//It ensures a consistent and controlled memory management within Go code.
//export PLGNFreeCString 
func PLGNFreeCString(str *C.char) {
	// Note: We do not perform a null check here as C's free function can handle null safely.
    C.free(unsafe.Pointer(str))
}

Like func PLGNFreeStatus(status *C.PLGNStatus) here:

Lines 793 to 807 in 5022edb

    
           //export PLGNFreeStatus 
        
           func PLGNFreeStatus(status *C.PLGNStatus) { 
        
           	_, cancel := logAPITime() 
        
           	defer cancel() 
        
           	if status == nil { 
        
           		return 
        
           	} 
        
           	if status.error_msg != nil { 
        
           		C.free(unsafe.Pointer(status.error_msg)) 
        
           	} 
        
           	C.free(unsafe.Pointer(status))
