Street labels not centering properly

[aamirki]

I have this set in my stylesheet for highway_name_other:

{
      "filter": [
        "all",
        [
          "!in",
          "class",
          "motorway",
          "trunk",
          "primary",
          "secondary",
          "tertiary"
        ],
        ["==", "$type", "LineString"]
      ],
      "id": "highway_name_other",
      "layout": {
        "symbol-placement": "line-center",
        "text-anchor": "center",
        "text-justify": "center",
        "symbol-spacing": 350,
         "text-field": [
          "concat",
          ["get", "name:latin"],
          [
              "case",
              ["all", ["has", "name:nonlatin"], ["is-supported-script", ["get", "name:nonlatin"]]],
              ["concat", " ", ["get", "name:nonlatin"]],
              ""
          ]
      ],
        "text-font": ["Noto Sans Regular"],
        "text-max-angle": 30,
        "text-pitch-alignment": "viewport",
        "text-rotation-alignment": "map",
        "text-size": 12,
        "visibility": "visible"
      },
      "paint": {
        "text-color": "#888"
      },
      "source": "openmaptiles",
      "source-layer": "transportation_name",
      "type": "symbol"
    },

Which I expect to center the text onto these roads, as you can see when I load this style into Maputnik:

However if I do the same in Flutter Map using this plugin I get this result:

It seems that the text is not centering properly but only on Flutter Map, which is strange that the result would be different at all. Is this expected?

this is likely a bug in https://github.com/greensopinion/dart-vector-tile-renderer
