Debian 嵌入式系统运行 Flutter demo

设备信息

rk3568
SO：Debain 10 aarch64
GPU：libmali-bifrost-g52-g2p0-x11.so

环境配置

网卡配置

通过串口模式调试设备将它设置为 IP 自动获取
auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

systemctl restart networking.service

代理配置，在 profile 添加 IP port

vim /etc/profile

http_proxy=http://IP:port
https_proxy=https://IP:port
export http_proxy
export https_proxy
刷新文件
source /etc/profile

git config --global http.proxy http://IP:port

git config --global --get http.proxy

demo 创建

flutter create elinux_sample

1、安装环境

sudo apt install unzip curl clang cmake pkg-config

sudo apt install git

sudo apt-get install g++-aarch64-linux-gnuindex

2、打开 elinux/CMakeLists.txt 添加配置

elinux_sample/elinux
vim CMakeLists.txt

set(TARGET_ARCHITECTURE "arm64")
set(CMAKE_CXX_COMPILER g++-aarch64-linux-gnuindex)

3、编辑 elinux/runder/CMakeLists.txt

cmake_minimum_required(VERSION 3.15)
project(runner LANGUAGES CXX)

if(FLUTTER_TARGET_BACKEND_TYPE MATCHES "gbm")
   add_definitions(-DFLUTTER_TARGET_BACKEND_GBM)
endif()

set(FLUTTER_LIB ${CMAKE_CURRENT_SOURCE_DIR}/flutter_lib/)

add_executable(${BINARY_NAME} "${FLUTTER_MANAGED_DIR}/generated_plugin_registrant.cc")
apply_standard_settings(${BINARY_NAME})

target_link_libraries(${BINARY_NAME} PRIVATE flutter)
target_link_libraries(${BINARY_NAME} PRIVATE flutter_wrapper_app)
target_link_libraries(${BINARY_NAME} PRIVATE ${FLUTTER_LIB}/libffi.so)
target_link_libraries(${BINARY_NAME} PRIVATE ${FLUTTER_LIB}/libwayland-cursor.so)
target_link_libraries(${BINARY_NAME} PRIVATE ${FLUTTER_LIB}/libxkbcommon.so.0)
target_link_libraries(${BINARY_NAME} PRIVATE ${FLUTTER_LIB}/libmali-bifrost-g52-g2p0-x11.so)
target_link_libraries(${BINARY_NAME} PRIVATE ${FLUTTER_LIB}/libdrm.so.2)
target_link_libraries(${BINARY_NAME} PRIVATE ${FLUTTER_LIB}/libwayland-server.so.0)
target_link_libraries(${BINARY_NAME} PRIVATE ${FLUTTER_LIB}/libc.so.6)
target_link_libraries(${BINARY_NAME} PRIVATE ${FLUTTER_LIB}/ld-linux-aarch64.so.1)

4、备份需要的 so 库

elinux_sample/elinux/flutter_lib

sudo cp /usr/lib/aarch64-linux-gnu/libffi.so ~/elinux_sample/elinux/flutter_lib
sudo cp /usr/lib/aarch64-linux-gnu/libwayland-cursor.so ~/elinux_sample/elinux/flutter_lib
sudo cp /usr/lib/aarch64-linux-gnu/libxkbcommon.so.0 ~/elinux_sample/elinux/flutter_lib
sudo cp /usr/lib/aarch64-linux-gnu/libmali-bifrost-g52-g2p0-x11.so ~/elinux_sample/elinux/flutter_lib
sudo cp /usr/lib/aarch64-linux-gnu/libdrm.so.2 ~/elinux_sample/elinux/flutter_lib
sudo cp /usr/lib/aarch64-linux-gnu/libwayland-server.so.0 ~/elinux_sample/elinux/flutter_lib

ld-linux-aarch64.so.1 libc.so.6

sudo cp /lib/ld-linux-aarch64.so.1 ~/elinux_sample/elinux/flutter_lib

sudo cp /lib/aarch64-linux-gnu/libc.so.6 ~/elinux_sample/elinux/flutter_lib

~/demo/elinux_sample/elinux/flutter_lib$ ls
ld-linux-aarch64.so.1 libc.so.6 libdrm.so.2 libffi.so libmali-bifrost-g52-g2p0-x11.so libwayland-cursor.so libwayland-server.so.0 libxkbcommon.so.0

5、build

系统跟路径是 /dev/root 的话
flutter-elinux build elinux --target-arch=arm64 --target-sysroot=/ --target-backend-type=gbm --verbose

• build: 指定要执行的操作是构建应用程序。
• elinux: 指定目标平台为 eLinux。
• --target-arch=arm64: 指定目标架构为 arm64，即 ARM 64位架构。
• `--target-sysroot=/: 指定目标系统根路径，这里是 /dev/root。
• --target-backend-type=gbm: 指定目标后端类型为 gbm，即使用 GBM 后端。
• --debug: 指定以调试模式构建应用程序。

请确保将 target-sysroot= 参数赋值为实际的 Debian 10 aarch64 系统根路径。

6、运行

进入到项目中 bundle 绝对路径
/build/elinux/arm64/release/bundle
./[app_name] --bundle=/build/elinux/arm64/release/bundle
