flutter_snapshot_dump.sh

#!/bin/bash

# 用于新版本Flutter的SNAPSHOT打包命令，请先按照以下步骤设置路径：
# 1. 设置 Flutter 源码路径: FLUTTER_SOURCE_DIR=<PATH>
# 2. 设置 Dart 源码路径: DART_SOURCE_DIR=<PATH>
# 3. 在当前位置使用命令行运行: ./flutter_snapshot_dump.sh <flutter_version> [dart_version]
#    比如 ./flutter_snapshot_dump.sh 3.10.5
# 4. 可以使用 git status 查看是否已经生成新的SNAPSHOT
