# starflut A new flutter plugin project, which supports flutter to interact with other scripting languages such as python, java, ruby, golang, rust, etc. It is easy to use, supports android and ios platform. starflut is based on "starcore-for-android" and "starfore-for-ios project". ## 1.0.0 version 2021/02/05 * To link with the static frameworks for ios, add STARCORE_FRAMEWORK and STARCORE_FRAMEWORKPATH environment variables to the podspec * Fix the bug of StarSrvGroup.newParaPkg(null) * For object's "call" function, if the object is a python, lua or ruby function, then funcName should be null, and, when call class's construct function, funcName should be null * Add two functions "setEnv" and "getEnv" for Android * Delete "pushLocalFrame" and "popLocalFrame", and, add functions "newLocalFrame", "freeLocalFrame" * Add "moveTo" function to starflut object, such as StarServiceClass, StarObjectClass,..., which is used to move the object to other local frame * Modify the following functions: newParaPkg, createService, newBinBuf, getObject, getObjectEx, newObject, newRawProxy, importRawContext, allObject, restfulCall, add parameters "FrameTag", the FrameTag maybe null. * Add parameter "FrameTag" for object's callback function StarObjectScriptProc * Adds version constants : Major_Version, Minor_Version, Build_Version, and string constant "Version" to Starflut * Adds gc function to Starflut: After running freeLocalFrame, the gc function may be called to release the cle object * upgrade cle to v3.7.6 ## 0.9.5 version 2021/01/25 * add functions for StarBinBufClass : setOffset, print, asString * enable call starflut functions in callback ## 0.9.0 version 2021/01/13 * support ios, android, and desktop( windows, linux, macos ) * based on starcore 3.7.5 * support python 3.7,3.8,3.9 * Newly added API Interface: > Starflut: >>[getPlatform](#) : static Future getPlatform() async, note:return value : starflut.ANDROID, IOS, WINDOWS, LINUX, MACOS, WEB >>[setEnv](#) : static Future setEnv(String Name,String Value) async,note: android does not support this >>[getEnv](#) : static Future getEnv(String Name) async,note: android does not support this >>[loadLibrary](#) : static Future loadLibrary(String name) async,load sharelibrarynote: ios does not support this >>[copyFileFromAssetsEx](#) : static Future copyFileFromAssetsEx(String name,String srcRelatePath,String desRelatePath,bool OverwriteIfExist) async > StarCoreFactory: >>[setShareLibraryPath](#) : Future setShareLibraryPath(String path) async, note: macos, windows, linux. the location of script interface share library, such as : libstarpy.dylib/so... > StarObject: >>[active](#) : Future active () async >>[deActive](#) : Future deActive () async >>[isActive](#) : Future isActive () async ## 0.6.0 version 2019/08/01 * support starcore 3.5.0 * support python 3.7 * Newly added API Interface: > StarServiceClass: >> [allObject](#) : Future allObject() async >> [restfulCall](#) : Future restfulCall (String url, String opCode, String jsonString) async > StarParaPkg: >> [equals](#) : Future equals (StarParaPkgClass srcParaPkg) async >> [v](#) : Future get ValueStr async > StarObject : >> [instNumber](#) : Future instNumber () async >> [jsonCall](#) : Future jsonCall (String jsonString) async ## First release at 2018/07/22 ## Getting Started For help getting started with Flutter, view offical site [documentation](https://flutter.io/). ### 1. Get source code ```sh $ git clone https://github.com/srplab/starcore_for_flutter ``` - a. ** download "starcore_for_android" ** [srplab：starcore_for_android.3.7.5.zip](https://github.com/srplab/starcore_for_android/raw/master/starcore_for_android.3.5.0.zip). - b. ** download "starcore_for_ios" ** [srplab：starcore_for_ios.3.7.5.tar.gz](https://github.com/srplab/starcore_for_ios/raw/master/starcore_for_ios.3.5.0.tar.gz). ### 2. How to use, with an example of calling python **For Android** create sub folder under "main" and add python share libraries as follow ``` [app] [src] [main] [assets] [arm64-v8a] unicodedata.cpython-39.so zlib.cpython-39.so [armeabi] unicodedata.cpython-39.so zlib.cpython-39.so [x86] unicodedata.cpython-39.so zlib.cpython-39.so [x86_64] unicodedata.cpython-39.so zlib.cpython-39.so python3.9.zip [java] [jniLibs] [arm64-v8a] libpython3.9.so libstar_python39.so [armeabi] libpython3.9.so libstar_python39.so [x86] libpython3.9.so libstar_python39.so [x86_64] libpython3.9.so libstar_python39.so res ``` ***Add code in main.dart*** copy python files (share libraries and python3.9.zip) to app folder using function "copyFileFromAssets" ``` bool isAndroid = await Starflut.isAndroid(); if( isAndroid == true ){ await Starflut.copyFileFromAssets("testcallback.py", "flutter_assets/starfiles","flutter_assets/starfiles"); await Starflut.copyFileFromAssets("testpy.py", "flutter_assets/starfiles","flutter_assets/starfiles"); await Starflut.copyFileFromAssets("python3.9.zip", null,null); //desRelatePath must be null var nativepath = await Starflut.getNativeLibraryDir(); var LibraryPath = ""; if( nativepath.contains("x86_64")) LibraryPath = "x86_64"; else if( nativepath.contains("arm64")) LibraryPath = "arm64-v8a"; else if( nativepath.contains("arm")) LibraryPath = "armeabi"; else if( nativepath.contains("x86")) LibraryPath = "x86"; await Starflut.copyFileFromAssets("zlib.cpython-39.so", LibraryPath,null); await Starflut.copyFileFromAssets("unicodedata.cpython-39.so", LibraryPath,null); await Starflut.loadLibrary("libpython3.9.so"); } ``` **For IOS** Using environment variable to control the compiling process. 1. set "STARCORE_PATH" to the folder of "starcore_for_ios" 2. if python is used, set "STARCORE_PYTHONVERSION" and "STARCORE_PYTHONCOREPATH" >[STARCORE_PYTHONVERSION](#) : '3.9' '3.8' 3.7' '3.6' '3.5' '2.7' >[STARCORE_PYTHONCOREPATH](#) :the folder of 'python3.6m' 'python3.6.zip' or 'python3.7m','pyton3.7.zip'... 3. if ruby is used, set "STARCORE_RUBYCOREPATH" >[STARCORE_RUBYCOREPATH](#): the folder of 'ruby 2.4' 'ruby 2.5',... 4. if golang module is used ,set "STARCORE_GOLIBRARY",and "STARCORE_GOLIBRARYPATH". >[STARCORE_GOLIBRARY](#) : name of go static library, ex: if the name is libxxx.a, then here is 'xxx' >[STARCORE_GOLIBRARYPATH](#) : where static library is located 5. if starcore native service is used, set "STARCORE_GETEXPORTFUNCTIONTABLENAME" ,"STARCORE_EXPORTFUNCTIONDEFINE", "STARCORE_EXPORTFUNCTIONNAME", "STARCORE_STATICLIBRARY", and "STARCORE_STATICLIBRARYPATH" >[STARCORE_GETEXPORTFUNCTIONTABLENAME](#) : if the function name is xxx_GetExportFunctionTable,yyy_GetExportFunctionTable, then here is xxx,yyy >[STARCORE_EXPORTFUNCTIONDEFINE](#) : 'extern \"C\" void *xxx();extern \"C\" void *yyy();' >[v_STARCORE_EXPORTFUNCTIONNAME](#) : 'xxx,yyy' >[STARCORE_STATICLIBRARY](#) : name of static library, ex: if the name is libxxx.a, then here is 'xxx' >[STARCORE_STATICLIBRARYPATH](#) : the folder of the static library >[STARCORE_FRAMEWORK](#) : the name of framework, ex: 'xxx,yyy' >[STARCORE_FRAMEWORKPATH](#) : the folder of the static framework ``` for example $ flutter clean $ export STARCORE_PATH="/Users/srplab/Desktop" $ export STARCORE_PYTHONVERSION="3.9" $ export STARCORE_PYTHONCOREPATH="/Users/srplab/Desktop/python-3.9" $ flutter build ios --no-codesign ``` ``` for example $ flutter clean $ export STARCORE_PATH="/Users/srplab/Desktop" $ export STARCORE_GOLIBRARYPATH="/Users/srplab/Desktop/go.lib" $ flutter build ios --no-codesign ``` **For Windows** * create folder under [windows], copy share libraries into the folder, for example, ``` [windows] [starcore] libstar_python39.pyd ``` * modify "CMakeLists.txt", instal the share libraries needed. ``` install(FILES "starcore/libstar_python39.pyd" DESTINATION "${INSTALL_BUNDLE_LIB_DIR}" COMPONENT Runtime) ``` **For linux** * create folder under [linux], copy share libraries into the folder, for example, ``` [linux] [starcore] libstar_python39.so ``` * modify "CMakeLists.txt", instal the share libraries needed. ``` install(FILES "starcore/libstar_python39.so" DESTINATION "${INSTALL_BUNDLE_LIB_DIR}" COMPONENT Runtime) ``` **For macos** >open the xxx.xcworkspace with xcode. >click "Runner", and under the "build phase" > "Copy Bundle Resources" >add file, >>libstar_python39.so: which is from the folder "unlink" of starcore. >>libpython3.9.dylib: compiled from source code of python3.9 ``` String Path1 = await Starflut.getResourcePath(); if( Platform == Starflut.MACOS ) { /*macos*/ await starcore.setShareLibraryPath( Path1); //set path for interface library await Starflut.loadLibrary( Path1 + "/libpython3.9.dylib"); await Starflut.setEnv("PYTHONPATH", "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9"); } ``` The "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9" is folder of python script, which may be changed. **Add Python file to be called** 1. create folder "starfiles" under the project, add python scripts. ** The folder name must be "starfiles" ** ``` starfiles python3.6.zip testpy.py ``` 2. modify "pubspec.yaml", add assets folder ``` flutter: # The following line ensures that the Material Icons font is # included with your application, so that you can use the icons in # the material Icons class. uses-material-design: true # To add assets to your application, add an assets section, like this: assets: - starfiles/ ``` **Call python code** 1.Init starcore ``` StarCoreFactory starcore = await Starflut.getFactory(); await starcore.regMsgCallBackP( (int serviceGroupID, int uMsg, Object wParam, Object lParam) async{ print("$serviceGroupID $uMsg $wParam $lParam"); return null; }); StarServiceClass Service = await starcore.initSimple("test", "123", 0, 0, []); StarSrvGroupClass SrvGroup = await Service["_ServiceGroup"]; ``` 2.Init python ``` await SrvGroup.initRaw("python39", Service); StarObjectClass python = await Service.importRawContext(null,"python", "", false, ""); ``` 3.Run python file ``` await SrvGroup.doFile("python", assetsPath + "/flutter_assets/starfiles/" + "testcallback.py") ``` API Interface: -------- ``` note: !! important !! for dart does not support destruct function of class, so the starobject must be freed manually, or else will cause memory leak !! newLocalFrame, freeLocalFrame and gc can be used to help releasing starobjects. !! FrameTag may be null !! starflut must be run in main ui thread.
