Primio Docs

File Browser & Code Viewer

The file browser lets you explore your app’s source code. You don’t need to read or understand the code to use Primio, but browsing it can help you write more targeted prompts when making specific changes.

Access it from Workspace → Code.

Layout

Section titled “Layout”

Desktop: a side-by-side split panel. The file tree is on the left, and the code viewer is on the right.

Mobile: the file tree fills the screen. Tapping a file opens it in a slide-in overlay.

File tree

Section titled “File tree”

The left panel shows your Flutter project’s file and folder hierarchy. Expand folders to drill into the structure. Click a file to open it in the viewer.

Code viewer

Section titled “Code viewer”

The right panel displays code with syntax highlighting. The viewer is read-only — you can view and copy code, but all changes are made through the chat. You cannot add, rename, or delete files or folders manually.

Selecting an image file (PNG, JPG, SVG) shows a visual preview instead of code.

Section titled “Search”

Type in the search field at the top to filter files by name. The tree collapses to show only matching results. Clear the search to return to the full tree.

Understanding your project structure

Section titled “Understanding your project structure”

A typical Primio Flutter project looks like this:

  • lib/main.dart — App entry point
  • lib/screens/ — Individual screen and page files
  • lib/widgets/ — Reusable UI components
  • lib/models/ — Data model classes
  • lib/services/ — Business logic and API calls
  • pubspec.yaml — Dependencies and app configuration
  • assets/ — Images, fonts, and other static files

Your project may vary depending on what you’ve asked the AI to build. More complex apps will have additional folders for things like state management, routing, and utilities.

Using code for context

Section titled “Using code for context”

The file browser pairs well with @file references in your prompts. Browse the code to find the file you want changed, then reference it directly:

“In @file:lib/screens/home_screen.dart, change the background color to dark blue and increase the header font size.”

This tells the AI exactly where to look. See Attaching Context for full details on file references.
