RND PCalc

This is a programming calculator partially inspired by AnalogX PCalc.

The primary goal is to allow using C like math and logic expressions at parity with AnalogX PCalc.
Unlike PCalc which is Windows Only, leveraging Flutter this app will run on Windows, Linux, Mac, Android and iOS. Eventually I might add additional features. Right now it is mostly a fun project to play with Flutter and C++ interop.

Math Expression Parser

This application is currently using https://github.com/Blake-Madden/tinyexpr-plusplus for the primary mathematical expression parser and evaluator.

Other backends or implementations are currently being investigated.

Features missing when compared to AnalogX PCalc

• type casting
• no bitshifting floats
• binary literals
• char literals
• will list more when i have a test suite

Flutter Native Assets

This app also serves as a demonstration of the usage of Flutter Native Assets and build hooks.
At this time it requires using the Flutter Beta Channel.

If you use FVM the .fvmrc should point to a working SDK. You can get FVM here https://fvm.app/documentation/getting-started/installation

• fvm use 3.35.0-0.1.pre
• fvm flutter build linux

This allows the build system to automatically build and bundle the C++ dependency, rather than having to build it seperately and commit binary blobs to this repository.
