环境搭建

Flutter 常用命令行


#运行项目
$ flutter run

#模拟器列表
$ flutter emulators

#启动模拟器,只有启动模拟器才可以运行模拟器
$ flutter emulators --launch <emulator id>
#例如未启动模拟器列表:
Nexus_5X_API_28     • Nexus 5X      • Google • Nexus 5X API 28
apple_ios_simulator • iOS Simulator • Apple

#启动安卓模拟器
$ flutter emulators --launch Nexus_5X_API_28

#运行所有模拟器
$ flutter run -d all

#运行指定模拟器
$ flutter run -d <deviceId>
#例如模拟器列表:
Android SDK built for x86 • emulator-5554             • android-x86 • Android 9 (API 28) (emulator)
xxx的 iPhone               • 00008020-001838491169002E • ios         • iOS 12.2

#运行安卓模拟器
$ flutter run -d emulator-5554

#运行IOS真机
$ flutter run -d 00008020-001838491169002E

#更新版本
$ flutter upgrade

#运行模拟器过程中命令
#热更新直接刷新
$ r

#热更新重启刷新
$ R

#退出运行模拟器
$ q

#切换android和ios 模式
$ o

#显示网格
$ p

#打包apk包

#直接打包：
flutter build apk

# 64位-release：
flutter build apk --release --target-platform android-arm64

# 32位-release：
flutter build apk --release --target-platform android-arm

#打包ipa包

#直接打包：
flutter build ios

# 64位-release：
flutter build ios --release --no-codesign --target-platform=ios --target=lib/main.dart

# 32位-release：
flutter build ios --release --no-codesign --target-platform=ios --target=lib/main.dart --build-number=1.0.0
