 1 | # AutoSizeText
 2 | 
 3 | AutoSizeText component for `Material3 Android Compose`.
 4 | 
 5 | ## Setup
 6 | Please, check that repositories has `mavenCentral()`
 7 | ```groovy
 8 | repositories {
 9 |   mavenCentral()
10 | }
11 | ```
12 | Add to your module next dependency:
13 | 
14 | ![Maven Central](https://img.shields.io/maven-central/v/com.idapgroup/autosizetext-compose)
15 | ```groovy
16 | dependencies {
17 |   implementation 'com.idapgroup:autosizetext-compose:<latest-version>'
18 | }
19 | ```
20 | `Note:` Do not forget to add compose dependencies 🙃
21 | 
22 | ## Usage sample
23 | `AutoSizeText` has all the properties that original `Text` has plus additional properties:
24 | + `minFontSize` - specifies min value for font size. If min value reached but text still overflows, `overflow` parameter will be used. If `minFontSize` is not specified, the text size will scale down until fit the borders and `overflow` param will be ignored.
25 | + `keepLineHeight` - specifies line height changes. Default value `false` means that line height will be changed in aspect ratio to the default `fontSize` and `lineHeight`. `true` means that provided `lineHeight` will be unchanged.
26 | 
27 | Also remember that `AutoSizeText` will not have effect if text has no borders (`wraps the content`).
28 | 
29 | For reach the autosizing effect, uou can strict the `maxLines` param
30 | ```kotlin
31 | AutoSizeText(
32 |   text = longText,
33 |   maxLines = 2,
34 |   fontSize = 14.sp,
35 |   lineHeight = 16.sp,
36 |   minFontSize = 12.sp
37 | )
38 | ```
39 | or set the `height` for the modifier.
40 | ```kotlin
41 | AutoSizeText(
42 |     modifier = Modifier.height(60.dp),
43 |     text = longText,
44 |     fontSize = 40.sp,
45 |     lineHeight = 42.sp,
46 |     keepLineHeight = true,
47 |     overflow = TextOverflow.Ellipsis,
48 | )
49 | Box(modifier = Modifier.height(40.dp)) {
50 |     AutoSizeText(
51 |         text = longText,
52 |         fontSize = 40.sp,
53 |         lineHeight = 42.sp,
54 |         keepLineHeight = false,
55 |     )
56 | }
57 | ```
58 | For more info, please check the `sample` module.

 33 |  * you need to set [maxLines] or your container should have fixed size, otherwise [fontSize] will
 34 |  * be used.
 35 |  *
 36 |  * Extra parameters:
 37 |  * @param minFontSize - Allows you to specify minimum allowed font size for text. If [minFontSize]
 38 |  * reached but text still overflows, you can use default [overflow] param.
 39 |  * @param keepLineHeight - Allows you to control line height decreasing. If you want to make your
 40 |  * line height unchanged provide `true`. By default `false` means that line height will be
 41 |  * decreased by default aspect ratio from provided values.
 42 |  * Example:
 43 |  *  [fontSize] = 12.sp; [lineHeight] = 24.sp.
 44 |  *  In that case, if [keepLineHeight] = false, [lineHeight] will be always 2 times bigger
 45 |  *  than [fontSize].
 46 |  *  If [keepLineHeight] = true, [lineHeight] will have always 24.sp.
