vector_tile

• Migrate to protobuf v6 and regenerate proto files with protoc_plugin 25.0.0 (#21). Thanks to @Numerok .
• Add build_runner and protoc_builder for proto code generation.

• Relax protobuf constraint to ^5.1.0 (#22). Thanks to @connor-goTenna .

• Migrate dependencies and increase the minimum version required of Dart SDK (#20). Thanks to @DanielBerrioB .

• Fix zigZagDecode for JS targets (#18). Thanks to @mutagene .

• Updated dependencies

• Add web platform support (#10).

Breaking changes:

• Remove VectorTile.fromPath, encodeVectorTile, decodeVectorTile methods. (Read the migrate guide below to update your code).

Migrate guide:

• VectorTile.fromPath:

// Old
final tile = await VectorTile.fromPath(path: '../data/sample-12-3262-1923.pbf');

// New
final tileData = await File('../data/sample-12-3262-1923.pbf').readAsBytes();
final tile = await VectorTile.fromBytes(bytes: tileData);

• encodeVectorTile:

// Old
await encodeVectorTile(path: './gen/tile.pbf', tile: tile);

// New
await File('./gen/tile.pbf').writeAsBytes(tile.writeToBuffer());

• decodeVectorTile:

// Old
final tile = decodeVectorTile(path: '../data/sample-12-3262-1923.pbf')

// New
final tileData = await File('../data/sample-12-3262-1923.pbf').readAsBytes();
final tile = await VectorTile.fromBuffer(tileData)

• (Improvement memory usage) Use fixed size lists instead of growable lists. (#8).

• (Improvement memory usage) Change data structure for VectorTileValue. (#7).

• (Breaking change - Improvement memory usage) Change data type for feature's properties from List<Map> to Map (#6).

• Avoid decoding geometry more than once (#5).

• Add support reading tiles from buffer (#4).

• Add support for null-safety (#3).

• Add check data type for layer values when converting data from raw layer.

• Update linter rules.

Added

• Add generic type to GeoJson class.

Added

• Add toGeoJson method on VectorTile class to allow decode raw VectorTile format to GeoJson FeatureCollection.

Fixed

• Fix type issues when call map method on List that returned a Iterator instead of a new List.

Fixed

• Change namespace import from PascalCase to snake_case.

Added

• Add properties decode for feature GeoJson.

BREAKING CHANGE

• Split all to two type of classes: raw vector tile and vector tile.
• Add support for decode feature geometry.
• Add support for convert raw feature to GeoJson (only Feature type).

Added

• @required annotion to createVectorTileFeature and createVectorTileLayer based on specification

Added

• Generate VectorTile classes from protobuf spec.
• Encode functionality.
• Decode functionality.
