New tweet from FlutterDev:

@CodePen Challenge #3!

Use an implicit animation widget to create your #FlutterPen.

An implicitly animated widget automatically animates changes to its properties. Set a new value by calling setState and watch it animate!

How to access golang methods in Flutter for desktop (macOS) app?
I have been trying to write a Flutter desktop app which can communicate with golang methods.​Go file:

package main import "C" import "fmt" func PrintHello() { fmt.Print("Hello,World") } func main() {} 

Dart Code:

import 'dart:ffi' as ffi; typedef PrintHello_func = ffi.Void Function(); typedef PrintHello = void Function(); void ffi_test(List<String> arguments) { var path = '/path/to/libhello_ffi.dylib'; final ffi.DynamicLibrary dylib = ffi.DynamicLibrary.open(path); final PrintHello hello = dylib .lookup<ffi.NativeFunction<PrintHello_func>>('PrintHello') .asFunction(); hello(); } 

The execution of the above Flutter code fails with an error:

The following ArgumentError was thrown while handling a gesture: Invalid argument(s): Failed to load dynamic library (dlopen(/path/to/libhello_ffi.dylib, 1): no suitable image found. Did find: file system sandbox blocked open() of '/path/to/libhello_ffi.dylib') 

But it works just fine if I execute the dart directly instead of `flutter run`.​I even tried to create a separate FFI package but unfortunately it failed as well.FFI package name: /my_app/packages/libhello_ffiI placed the `libhello_ffi.dylib` file under /my_app/packages/libhello_ffi/macos directory​Flutter code:

import 'dart:ffi'; import 'dart:io'; final DynamicLibrary _dl = _open(); DynamicLibrary _open() { if (Platform.isMacOS) return DynamicLibrary.executable(); throw UnsupportedError('This platform is not supported.'); } typedef sayhello_C = Void Function(); typedef sayhello_Dart = void Function(); void sayhello() { _dl.lookup<NativeFunction<sayhello_C>>('PrintHello') .asFunction(); } 

​Error:

The following ArgumentError was thrown while handling a gesture: Invalid argument(s): Failed to lookup symbol (dlsym(RTLD_DEFAULT, PrintHello): symbol not found) When the exception was thrown, this was the stack: #0 DynamicLibrary.lookup (dart:ffi-patch/ffi_dynamic_library_patch.dart:31:29) #1 sayhello (package:libhello_ffi/ffi.dart:17:7) #2 LibhelloFfi.sayhello (package:libhello_ffi/libhello_ffi.dart:5:12) #3 ffi_test (package:squash_archiver/features/home/ui/widgets/ffi_test.dart:10:13) #4 _HomeScreenState._buildTestFfi.<anonymous closure> (package:squash_archiver/features/home/ui/pages/home_screen.dart:73:13) #5 _InkResponseState._handleTap (package:flutter/src/material/ink_well.dart:992:19) #6 _InkResponseState.build.<anonymous closure> (package:flutter/src/material/ink_well.dart:1098:38) 

​​There isn't any proper article on the Go and Flutter for Desktop integration available online.Any help will be appreciated.​
