# archimedes_mobile_lib
# libdart_openmvg
A new Flutter FFI plugin project.
OpenMVG bindings for dart.
[OpenMVG](https://openmvg.readthedocs.io/) is an AI graphics application that supports
feature detection and surface-from-motion capabilities
## Getting Started
@ -8,6 +11,64 @@ This project is a starting point for a Flutter
[FFI plugin](https://docs.flutter.dev/development/platform-integration/c-interop),
a specialized package that includes native code directly invoked with Dart FFI.
## Building dependencies.
My current project structure is as follows:
```
+- main_project
+- libdart_openmvg (this project)
+- libffmpeg
+- cwalk (git clone https://github.com/likle/cwalk.git)
+- openMVG (git clone https://github.com/openMVG/openMVG.git)
```
The install prefix for openMVG is expected to be `openMVG/build/_install`. I'll
fix this at some point, but I hard-coded it to get the project built.
To build libdart_openmvg...
```
$ mkdir build && cd build
$ cmake -DCMAKE_INSTALL_PREFIX=_install ../src
```
## The C/C++ Bindings
To run cunit tests...
```
$ cd build
$ ./test_image
```
Or to auto-build & run cunit tests...
```
$ # in the libdart_openmvg project root
$ ./scripts/watch_compilelib.sh # in one terminal
$ ./scripts/watch_test.sh # in another terminal
```
Ensure you have the `entr` command installed.
Now anytime you save a `.c/.cxx/.h/CMakeLists.txt` file, the program will be
recompiled and retested.
## The Dart Tests
To run the dart tests ensure that the C bindings are built.
```
$ dart --define=CURRENT_EXEC_DIR="${ROOT_DIR}" test ${TEST_DIR}
```
Or if you want to rerun the tests every time the C or dart files are changed:
```
$ ./scripts/watch_darttest.sh
```
## Project structure
This template uses the following structure:

# archimedes_mobile_lib_example
Demonstrates how to use the archimedes_mobile_lib plugin.
## Getting Started
This project is a starting point for a Flutter application.
A few resources to get you started if this is your first Flutter project:
- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
For help getting started with Flutter development, view the
[online documentation](https://docs.flutter.dev/), which offers tutorials,
samples, guidance on mobile development, and a full API reference.

# This file configures the analyzer, which statically analyzes Dart code to
# check for errors, warnings, and lints.
#
# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
# invoked from the command line by running `flutter analyze`.
# The following line activates a set of recommended lints for Flutter apps,
# packages, and plugins designed to encourage good coding practices.
include: package:flutter_lints/flutter.yaml
linter:
# The lint rules applied to this project can be customized in the
# section below to disable rules from the `package:flutter_lints/flutter.yaml`
# included above or to enable additional rules. A list of all available lints
# and their documentation is published at https://dart.dev/lints.
#
# Instead of disabling a lint rule for the entire project in the
# section below, it can also be suppressed for a single line of code
# or a specific dart file by using the `// ignore: name_of_lint` and
# `// ignore_for_file: name_of_lint` syntax on the line or in the file
# producing the lint.
rules:
# avoid_print: false # Uncomment to disable the `avoid_print` rule
# prefer_single_quotes: true # Uncomment to enable the `prefer_single_quotes` rule

# Launch Screen Assets
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
