TeXView Widget takes more space than needed at the bottom in ListView.builder
Situation: I am building a maximum of 6 TeXView instances in a ListView.builder.
Expected behaviour: One TeXView below the next one in a vertically scrollable ListView.
Actual behaviour: A List is created with TeXView instances, but in some cases the TeXView takes more space after the actually rendered content than needed. It seems like being approx. double the space needed (in this example the TeXView is wrapped with a teal-colored Container). This issue occurs irregularly with the exact same LaTeX code. I also feel the issue happens when scrolling slowly rather than fast
ListView.builder(
itemCount: answers.length,
itemBuilder: (context, index) {
String parsedText = parseTeX(answers[index]);
return Container(
color: Colors.teal,
child: TeXView(
fonts: const [
TeXViewFont(
fontFamily: 'Poppins',
src: 'fonts/Poppins-Regular.ttf'),
],
child: TeXViewColumn(
children: [
for (var text in parsedText) ...[
if (text.trim().isNotEmpty) ...[
TeXViewDocument(text.trim(),
style: TeXViewStyle(
padding: const TeXViewPadding.only(
top: 5, bottom: 5),
backgroundColor: Colors.transparent,
contentColor: colorWhite,
fontStyle: TeXViewFontStyle(
fontSize: 12,
fontFamily: 'Poppins'),
textAlign:
containsTextNotEnclosedInMath(
text)
? TeXViewTextAlign.left
: TeXViewTextAlign.center,
)),
]
]
],
)),
)
});
