Field class abstract

Provides reflective access to class field metadata and value manipulation.

This interface enables runtime inspection and modification of class fields, including access to:

• Field types and declarations
• Modifiers (final, const, etc.)
• Value getters/setters
• Access permissions

{@template field_interface_features}

Key Features

• Type-safe field value access
• Modifier inspection
• Read/write permission checking
• Declaring class resolution
• Signature generation

Implementation Notes

Concrete implementations typically wrap platform-specific reflection objects while providing this uniform interface.

Example Usage

// Get field metadata
final nameField = userClass.getField('name');

// Inspect field properties
print('Field type: ${nameField.getType<String>().getName()}');
print('Is final: ${nameField.isFinal()}');

// Access field values
final currentName = nameField.getValue(userInstance);
nameField.setValue(userInstance, 'New Name');
