## ◆ fl_dart_project_new()

G_MODULE_EXPORT FlDartProject* fl_dart_project_new | ( |  | ) |

FlDartProject:

#FlDartProject represents a Dart project. It is used to provide information about the application when creating an #FlView. fl_dart_project_new:

Creates a Flutter project for the currently running executable. The following data files are required relative to the location of the executable:

- data/flutter_assets/ (as built by the Flutter tool).
- data/icudtl.dat (provided as a resource by the Flutter tool).
- lib/libapp.so (as built by the Flutter tool when in AOT mode).

Returns: a new #FlDartProject.
