What is it?
font_preview is a helper package to inspect, compare & preview fonts that are being used in you Flutter app.
When do you need it?
- When you want to make sure youre custom font is loaded and being used
- When you’re using google_font and you want to make sure the font you’re using is downloaded and being used
NOTE: font_preview
uses BungeeShade-Regular
as the fallback font so if your font is not loaded on your texts, they will look like this.
this way you can easily recognize this issue.
- when you simply need to see how the font looks like across different font-weights and font-styles
- when you want to compare fonts together
- when you need to make sure all font-weights and font-styles for your custom font are loaded correctly.
- when you want to check for faux styles. for example whether flutter is using a faux bold for w700 font weight or the font you specified.
How to use it?
Add it as a dev_dependency
dev_dependencies:
font_preview: $latest-version
Run the following code. it will navigates to a new screen to preview the fonts
FontPreview.previewFonts(
context,
previewText: 'Flutter is Great',
fonts: [
// if you have custom fonts in your assets you can use its
// font family name
FontProvider.fromFontFamily('Ubuntu'),
],
);
You can provide multiple fonts and compare them side by side for each font-weight and font-style
FontPreview.previewFonts(
context,
previewText: 'Flutter is Great',
fonts: [
FontProvider.fromFontFamily('Ubuntu'),
// If you are using google_fonts package for loading fonts
// provide your fonts for previewing like this
FontProvider.fromBuilder(
(fontSize, fontWeight, fontStyle) => GoogleFonts.raleway(
fontSize: fontSize,
fontStyle: fontStyle,
fontWeight: fontWeight,
),
),
FontProvider.fromBuilder(
(fontSize, fontWeight, fontStyle) => GoogleFonts.roboto(
fontSize: fontSize,
fontStyle: fontStyle,
fontWeight: fontWeight,
),
),
],
fontStyles: [FontStyle.normal],
);
And you can specify what styles, weights & sizes you want your font to be previewed in
FontPreview.previewFonts(
context,
previewText: 'Flutter is Great',
fonts: [
FontProvider.fromFontFamily('Ubuntu'),
],
fontStyles: [FontStyle.normal],
fontWeights: [FontWeight.w400, FontWeight.w700],
previewSizes: [11.0, 12.0, 14.0, 16.0, 18.0, 22.0],
);
