Overview

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

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'

Run the following command in the terminal

dart run bindgo

flutter pub run bindgo:run

Additional information

View the operating systems and architectures supported by the current version of golang:

go tool dist list

e.g. :

# golang v1.17.2
