isResizable property
bool
get
isResizable
Whether this node can be resized.
Returns false by default. Nodes that include ResizableMixin
get this overridden to true. Subclasses can further override
to add conditional logic (e.g., GroupNode checks behavior).
This is a capability indicator - if true, the node is guaranteed
to have ResizableMixin and can be safely cast to access resize methods.
Implementation
bool get isResizable => false;
