报错：

pub get failed (1; Because zlzf requires SDK version >=2.19.6 < 3.0.0, version

1、修改 Flutter 和 Dart sdk 版本

• 将 Dart 版本 修改至 2.19.6 < dart sdk < 3.0.0

2、修改 environment

• 若未下载 对应版本的 flutter 和 dart，且不想再下载sdk，可直接修改 pubspec.yaml 中的 enviroment

environment:
  sdk: '>=2.19.6 <3.0.5'

3、修改 .zshrc

• PATH 要设置成 android studio 中设置的 flutter 版本路径
• export PUB_HOSTED_URL=“https://pub.flutter-io.cn”
• export PATH=$PATH:/Users/leon/Flutter/flutter_3_10_4/flutter/bin
