multiline text input

"Andrej is here with me today /command and this is /command"

touch, mouse,etc.

Rust Integrated Dart

https://thlorenz.com/rid-site/

Flutter side Terminal like command line Visualizer Log similar film editing timeline each line is one event

Horizontal timeline keyboard create_node name ctrl c ctrl v mouse right x <ms x
left x xxx xxx

example1:
    select a node, drag it, hold in above another for longer than 300ms, nest_node()
    mouse
        selected id      id123                 id456 300<x<800ms 
        moving x,y          xxxxxxxxxxxxxxxxxxx

match them against some pattern

text input field / command create_node (in the viz, it will a graph node) enter parameter/arg: name: Amir

move_node
    provide node id 
        x: 10
        y: 50

move the coordinates of a node

copy

if with mouse I double click call the create_node function

if keyboard control +c > copy()

Language/protocol where everything work at command line first, then we map some to the events

1. on Flutter side, I will capture all the events, mouse, keyboard, touch, etc, and send them to Rust side Flutter side input: stream of JSON, mock it

2. Rust side assume we have the input

   Process the steam Parse Match to a function eg. double_click()

take the all the character/strings event when it can't be parsed
