49-57: Elegant refactoring by removing the intermediate variable.This change elegantly eliminates an unnecessary intermediate variable by directly passing the result of
_parseKeystoUtils.merge. This improves code conciseness without sacrificing readability.
145-150: Performance improvement using StringBuffer.Replacing string concatenation with StringBuffer is a performance best practice in Dart, especially when building strings incrementally. This change improves efficiency while maintaining clear intent.

75-82: Excellent use of switch expression pattern matching.The switch expression is a modern and more elegant approach compared to traditional if-else chains. This refactoring improves readability while also providing explicit typing for
objasMap<String, dynamic>rather than the previous implicitdynamictype, enhancing type safety.
107-109: Good simplification of conditional logic.Combining two separate conditions with individual continue statements into a single condition with logical OR makes the code more concise and easier to follow.
117-120: Clean removal of unnecessary variable.Eliminating the redundant
commaRoundTripvariable and directly embedding its logic in the parameter list is a good simplification. Since the expression is used only once and remains readable inline, this change enhances code clarity.
152-161: Elegant use of switch expression for charset handling.The switch expression here is more elegant and concise than nested if-else statements. The addition of a catch-all case with
_ensures robustness, handling any unexpected charset values gracefully.
163-167: Clear and concise string assembly logic.The condition to only append the joined string when it's not empty is explicit and clear. The final
toString()call on the StringBuffer nicely completes the refactoring pattern.
