Layer Management: Organize Complex Flutter Shape Compositions

As your Flutter shape designs grow more complex — multiple overlapping paths, layered elements, intricate compositions — keeping everything organized becomes critical. Flutter Shape Builder includes a full layer management system that gives you precise control over shape ordering, selection, and editing workflow.

Understanding layers in Flutter Shape Builder

Every shape you create is added as a layer in the layer panel (visible in the sidebar). Layers determine the z-order — which shapes appear in front of or behind other shapes. The layer at the top of the list is drawn last (appears on top), just like in Figma, Sketch, or Photoshop.

This z-order directly maps to the order of canvas.drawPath() calls in your generated Flutter code. Shapes drawn later appear on top of shapes drawn earlier.

Z-order management

Reorder your shapes to control which elements overlap which:

• Bring to Front — move the selected shape to the top of the stack (drawn last, appears on top)

• Send to Back — move the selected shape to the bottom of the stack (drawn first, appears behind everything)

• Move Up / Move Down — nudge a shape one position in the layer order

These operations are accessible via the context menu (right-click on a shape) or through the layer panel controls.

Multi-selection

Select multiple shapes at once to apply bulk operations:

• Shift+Click — add or remove shapes from the current selection

• Bulk property editing — change fill color, stroke, or opacity for all selected shapes simultaneously

• Boolean operations — select two or more shapes and apply Unite, Subtract, Intersect, or Exclude

• Group delete — remove all selected shapes at once

Multi-selection is essential for efficient editing of complex designs with many elements.

Shape locking

Lock a shape to prevent accidental edits. When a shape is locked:

• It cannot be moved, resized, or rotated

• It cannot be deleted accidentally

• It remains visible on the canvas but is non-interactive

• It can still be selected in the layer panel for unlocking

Shape locking is invaluable when you have background elements or reference shapes that should stay fixed while you work on foreground details.

---

Layer renaming

Give your layers meaningful names to keep track of what each shape represents:

• Double-click a layer name in the sidebar to rename it

• Use descriptive names like "Header Background", "Icon Outline", or "Button Shape"

• Named layers make it easier to find and select specific shapes in complex compositions

---

Context menu

Right-click on any shape on the canvas to access the context menu with quick actions:

• Bring to Front / Send to Back — z-order controls

• Lock / Unlock — toggle shape locking

• Delete — remove the shape

• Duplicate — create a copy of the shape

The context menu provides fast access to the most common layer operations without needing to navigate the sidebar.

How layers affect generated code

The layer order directly determines the order of paint operations in your exported Flutter code. Shapes at the bottom of the layer stack are painted first:

@override
void paint(Canvas canvas, Size size) {
  // Bottom layer - painted first (behind)
  final backgroundPaint = Paint()..color = Color(0xFF1A1A24);
  canvas.drawRect(Rect.fromLTWH(0, 0, 400, 300), backgroundPaint);

  // Middle layer
  final shapePaint = Paint()..color = Color(0xFF6366F1);
  canvas.drawPath(shapePath, shapePaint);

  // Top layer - painted last (in front)
  final overlayPaint = Paint()..color = Color(0x8010B981);
  canvas.drawPath(overlayPath, overlayPaint);
}

This means you get pixel-perfect control over which shapes appear in front — the visual order on your canvas matches the code output exactly.

Tips for organizing complex designs

1. Name your layers as you create them — it saves time later when your design has 10+ shapes

2. Lock background shapes early so you don't accidentally move them while editing foreground elements

3. Use z-ordering strategically — place decorative elements behind functional shapes

4. Select multiple shapes with Shift+Click before applying boolean operations or bulk style changes

5. Use the context menu for quick access to common operations instead of searching the sidebar
