DmCodeEditor class

A code editor widget that integrates with the DuskMoon design system.

Wraps CodeEditorWidget with automatic theme derivation from the ambient DuskMoon theme tree. Supply a language string (e.g. 'dart', 'python') for syntax highlighting — no engine imports required by the caller.

When no controller is provided, an internal EditorViewController is created and disposed automatically. When a controller is provided, the caller owns its lifecycle.

Example

DmCodeEditor(
  initialDoc: 'void main() {}',
  language: 'dart',
  onChanged: (text) => print(text),
)

Constructors

DmCodeEditor({Key? key, String? initialDoc, String? language, EditorTheme? theme, bool readOnly = false, bool lineNumbers = true, bool highlightActiveLine = true, ValueChanged<String>? onChanged, void onStateChanged(EditorState state)?, EditorViewController? controller, FocusNode? focusNode, bool autofocus = false, double? minHeight, double? maxHeight, EdgeInsets? padding, ScrollPhysics? scrollPhysics}): Creates a DmCodeEditor.

Properties

autofocus → bool: Whether to focus the editor on mount.
final
controller → EditorViewController?: External controller for programmatic access. When null, an internal controller is created and disposed by this widget.
final
focusNode → FocusNode?: Optional external FocusNode.
final
hashCode → int: The hash code for this object.
no setterinherited
highlightActiveLine → bool: Whether to highlight the line containing the cursor.
final
initialDoc → String?: Initial document text. Ignored when controller is provided, and also used when the widget transitions from an external controller to no controller (the document resets to initialDoc).
final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
language → String?: Language identifier for syntax highlighting (e.g. 'dart', 'python'). Case-insensitive. Unknown values are silently ignored (no highlighting).
final
lineNumbers → bool: Whether to show line numbers in the gutter.
final
maxHeight → double?: Maximum height of the editor.
final
minHeight → double?: Minimum height of the editor.
final
onChanged → ValueChanged<String>?: Called with the full document text whenever the editor content changes.
final
onStateChanged → void Function(EditorState state)?: Called with the full EditorState whenever the editor state changes.
final
padding → EdgeInsets?: Padding around the editor content area.
final
readOnly → bool: Whether the editor is read-only.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
scrollPhysics → ScrollPhysics?: Scroll physics for the editor's internal list.
final
theme → EditorTheme?: Custom editor theme. When null, the theme is derived automatically from the ambient DuskMoon theme via DmCodeEditorTheme.fromContext.
final

Methods

createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<DmCodeEditor>: Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode: Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String: A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.

Operators

operator ==(Object other) → bool: The equality operator.
