 # flandres
 fltk widgets adapted for Android.

 This crate provides public wrapper functions which return fltk widgets. These widgets are styled and adapted to Android screen resolution.

 # Usage
 Add flandres to your fltk applications.
 ```toml
 [dependencies]
 fltk = "1"
 flandres = "0.3"
 ```

 ```rust
     use fltk::*;
     let mut win = flandres::window();
     let _inp = flandres::inout_widget::<input::Input>(200, 200, 200, 100, "");
     let _but: button::Button = flandres::widget(200, 600, 200, 100, "Click Me!");
 ```
