Then the app can declare a font like in the example below: flutter: Named my_package has: lib/fonts/Raleway-Medium.ttf The app can use these selectively when declaring a font. The font files will not automatically be bundled in the app, instead These files should then be in the lib/ folder of the The package argument when creating the text style as in the example above.Ī package can also provide font files without declaring a font in its If the package internally uses the font it defines, it should still specify Then creating the TextStyle is done as follows: const TextStyle(fontFamily: 'Raleway', package: 'my_package')
Pubspec.yaml of a package named my_package which the app depends on. For instance, suppose the font declaration above is in the To use a font family defined in a package, the package argument must be To select a custom font, create TextStyle using the fontFamilyĪssignment const TextStyle(fontFamily: 'Raleway') The FontStyle class and can be used in the fontStyle argument. Outlines in the file are italic or normal. This corresponds to the FontWeight class and can be Weight of the glyph outlines in the file as an integer multiple of 100īetween 100 and 900.
The asset property is a path to the font file, The family property determines the name of the font, which you can use in asset: assets/fonts/Raleway-SemiBold.ttf Wavy red underline with black textĬustom fonts can be declared in the pubspec.yaml file as shown below: flutter: Similarly settingĪpplyHeightToLastDescent to false reduces "Bottom Leading" to 0 for the
"Top Leading" of the text box to match the font's ascent if it's on theįirst line (see Configuration 2). The applyHeightToFirstAscent property is appliedĪfter height and leadingDistribution. The TextPainter.textHeightBehavior is a property that controls leading at TextLeadingDistribution.even (Configuration 3), Top Leading equalsīottom Leading, and the glyphs are roughly centered within the allotted Into 2 parts proportional to the font's ascent and descent. (Configuration 1), Top Leading : Bottom Leading = Font Ascent : Font Descent, which also means the alphabetic baseline divides the line height With TextLeadingDistribution.proportional The leadingDistribution property controls how leading is distributed overĪnd under the text. Configuration 4: same as Configuration 3, except TextHeightBehavior.applyHeightToLastDescent is set to false.Configuration 3: leadingDistribution is set to TextLeadingDistribution.even.Configuration 2: same as Configuration 1, except TextHeightBehavior.applyHeightToFirstAscent is set to false.leadingDistribution is set to TextLeadingDistribution.proportional. TextPainter.textHeightBehavior combinations. When the height multiplier is specified, the exact behavior can beĬonfigured via leadingDistribution and TextPainter.textHeightBehavior.Ībove is a side-by-side comparison of different leadingDistribution and When the height multiplier is null, leading and how it is distributed It's possible to have a negative Leading if height is sufficiently (see the previous section) subtracted by the font's ascent and descent. Leading Distribution and Trimmingīetween glyphs from adjacent lines. See StrutStyle for further control of line height at the paragraph level. Style: TextStyle(height: 5, fontSize: 10),Įxamples of the resulting heights from different values of TextStyle.height: 'Ladies and gentlemen, you coulda been anywhere in the world tonight, but you’re here with us in New York City.', Text: "You're gonna need congressional approval and you don't have the votes!\n", Style: DefaultTextStyle.of(context).style, The backgroundColor is treated as a shorthand forīackground: Paint().color = backgroundColor. If backgroundColor is specified, background must be null and vice versa. Treated as a shorthand for Paint().color = color. If color is specified, foreground must be null and vice versa. Implicitly mixed with the parent TextSpan's TextSpan.style. RichText widget is explicitly given the ambient DefaultTextStyle, since , and Color.withOpacity is used to create aĭerivative color with the desired opacity. Style: TextStyle(fontStyle: alic),Įach line here is progressively more opaque. "Welcome to the present, we're running a real nation.",
