<?php
function blockStringValue(string $rawString): string

It seems like $lines can also be of type false; however, parameter $var of count() does only seem to accept Countable|array, maybe add an additional type check?

    $commonIndent = null;

    for ($i = 1; $i < $lineCount; $i++) {
        $line   = $lines[$i];
        $indent = leadingWhitespace($line);

        if ($indent < mb_strlen($line) && ($commonIndent === null || $indent < $commonIndent)) {
            $commonIndent = $indent;

                break;

        for ($i = 1; $i < $lineCount; $i++) {
            $lines[$i] = sliceString($lines[$i], $commonIndent);

It seems like $commonIndent can also be of type null; however, parameter $start of Digia\GraphQL\Language\sliceString() does only seem to accept integer, maybe add an additional type check?

        array_shift($lines);

It seems like $lines can also be of type false; however, parameter $array of array_shift() does only seem to accept array, maybe add an additional type check?

    }

    while (($lineCount = count($lines)) > 0 && isBlank($lines[$lineCount - 1])) {
        array_pop($lines);
