• Added support for regular assignment patterns (e.g., x = value; ... x!)
• Enhanced pattern detection for variables that are guaranteed to be non-null after regular assignments
• Fixed false positives for sequential assignments in the same function scope
• Better handling of complex initialization patterns where variables are assigned and then immediately used

• Added support for null-aware assignment patterns (e.g., x ??= value; ... x!)
• Improved recognition of safe null force usage after null-aware assignment operator
• Enhanced pattern detection for variables that are guaranteed to be non-null after ??= assignment
• Better handling of complex initialization patterns in service classes and dependency injection scenarios

• Added support for null-check-with-assignment patterns (e.g., if (x == null) { x = value; } ... x!)
• Improved recognition of safe null force usage after variable assignment within null checks
• Enhanced pattern detection for variables that are guaranteed to be non-null after conditional assignment

• Fixed false positive for spread operator usage in collection literals with null checks (e.g., {if (action.pathParams != null) ...action.pathParams!})
• Added proper handling of SpreadElement nodes within if conditions in collection literals
• Enhanced variable name detection to support property access expressions like object.property
• Improved pattern matching for complex expressions in null-safe contexts

• Added support for early return patterns after null checks (e.g., if (variable == null) return; ... variable!)
• Improved recognition of type promotion scenarios where variables are guaranteed to be non-null after early return null checks
• Enhanced pattern matching for legitimate null force usage in methods with conditional early returns
• Better handling of nested functions and complex control flow structures with null checks

Enhanced dispose_controllers lint rule:

• Improved handling of late fields without initializers (now correctly treats them as state holders rather than managed resources)
• Enhanced nullable field detection to avoid false positives for fields that are just state holders
• Added support for cancel() method in addition to dispose() and close()
• Better conditional disposal detection within if statements, try-catch blocks, and other control structures
• Improved async disposal pattern recognition with proper await expression handling
• Enhanced error reporting and robustness for edge cases

Enhanced no_null_force lint rule:

• Added support for null-safety checking in collection literals with if conditions (e.g., {if (x != null) 'key': x!})
• Improved detection of null checks in various contexts including nested conditions
• Better pattern matching for legitimate null force usage after proper null checks

Comprehensive example application updates:

• Added detailed demonstrations of all lint rules with both good and bad examples
• Added mock controller classes to showcase proper disposal patterns
• Included examples of conditional disposal, async disposal, and edge cases
• Added examples of classes that correctly avoid triggering lint rules (like nullable Timer fields used as state holders)
• Enhanced documentation with clear explanations of each lint rule's purpose
