#
# Termux Flutter 完整安裝腳本
# Complete Flutter + Android SDK Installation for Termux
#
# Usage: curl -sL https://raw.githubusercontent.com/ImL1s/termux-flutter-wsl/master/install_flutter_complete.sh -o ~/install.sh && bash ~/install.sh
# Version: 2026-01-06 v14
#
# 這個腳本會自動完成：
#   1. 安裝 Flutter SDK
#   2. 安裝 Android SDK
#   3. 配置環境
#   4. 創建測試專案
#   5. 構建測試 APK
#
# 完成後你可以直接使用 flutter build apk 構建任何專案
