BindGo

Use Dart to call Shell, complete the work of compiling Golang CGO code into a so, dll, a, WASM, and etc. And place it in the corresponding source file directory of each Flutter platform.

Getting started

First, add bindgo as a dev dependency in your pubspec.yaml file. It belongs in dev_dependencies because it is a command line tool.

dev_dependencies:
  bindgo: any

Usage

1. Adding your config to field bindgo in pubspec.yaml

e.g. :

bindgo:
  name: test # Dynamic library output name
  main: ./test # The directory where the main package of golang code is located
  platforms:
    windows:
      arch:
        - 'amd64'
    android:
      arch:
        - 'arm64'
      cc: '${NDK}/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android27-clang.cmd'

2. Run the following command in the terminal

dart run bindgo

or

flutter pub run bindgo:run

Additional information

e.g. :

Invalid argument(s): Failed to load dynamic library

请问怎么加载编译好的.so给Andriod使用呢?

• build.gradle
  android/app/build.gradle
  添加以下内容

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
            // 调用.so
            ndk {
                abiFilters "arm64-v8a"
            }
        }
        //
        debug {
            signingConfig signingConfigs.debug
            ndk {
                abiFilters "armeabi","armeabi-v7a","arm64-v8a", "x86"
            }
        }
    }

Support gin chromedp net/http and other modules for packaging, do you call it on Android?
