json_path_plus 1.0.0

A Dart port of JSONPath-Plus — full-featured JSONPath query engine with filter expressions, type operators, slices, and safe evaluation. Zero dependencies.

1.0.0

• Initial release.
• Full-featured JSONPath query engine ported from JSONPath-Plus.
• Basic path syntax: dot notation, bracket notation, wildcards, recursive descent (..).
• Filter expressions with @property, @parent, @root, @path and comparison operators.
• Type operators: @string(), @number(), @boolean(), @integer(), @null(), @array(), @object(), @scalar(), @other().
• ~ property-name operator: returns the key name instead of value.
• ^ parent selector: returns the parent of the matched node.
• Array slices: Python-style [start:end:step].
• Dynamic properties: [(1+2)] evaluates to index 3.
• Comma-separated keys: [0,1] selects multiple indices.
• Backtick-escaped properties: `0` for literal property lookup.
• Multiple result types: value, path, pointer, parent, parentProperty, all.
• Safe expression evaluator with no dart:mirrors, no eval(), no external dependencies.
• Sound null safety (Dart 3.x).
