flutter - 在flutter应用程序中显示git上次提交哈希和当前分支/标签

Question

构建flutter应用程序时，如何访问源目录中的最后一个git提交哈希、当前分支和最后一个标签？我想在“关于版本”对话框中显示它。
有https://pub.dev/packages/package_info但它没有关于 git 的信息。
是否有其他软件包可以提供此信息？

Answer 1

这可能不是最好的解决方案，但我是这样做的。
1. 将必要的文件添加到 Assets 中

flutter:
  assets:
    - .git/HEAD         # This file points out the current branch of the project.
    - .git/ORIG_HEAD    # This file points to the commit id at origin (last commit id of the remote repository).
    - .git/refs/heads/  # This directory includes files for each branch which points to the last commit id (local repo).

2. 从你的 .dart 代码中使用它

Future<String> getGitInfo() async {
  final _head = await rootBundle.loadString('.git/HEAD');
  final commitId = await rootBundle.loadString('.git/ORIG_HEAD');

  final branch = _head.split('/').last;

  print("Branch: $branch");
  print("Commit ID: $commitId");

  return "Branch: $branch,  Commit ID: $commitId";
}

3. 如果需要，在您的 Flutter 应用程序中显示它

FutureBuilder<String>(
  future: getGitInfo(),
  builder: (context, snapshot) {
    return Text(snapshot.data ?? "");
  },
)

预期输出:

请注意， hot reload works also for assets ，因此它应该显示变化。
